UART Interface BlueCore4-External Universal Asynchronous Receiver Transmitter (UART) interface provides a simple mechanism for communicating with other serial devices using the RS232 (1) standard . BlueCore4-External Figure 11.12: Universal Asynchronous Receiver Four signals are used to implement the UART function, as shown in Figure 11.12. When BlueCore4-External is connected to another digital device, UART_RX and UART_TX transfer data between the two devices. The remaining two signals, UART_CTS and UART_RTS, can be used to implement RS232 hardware flow control where both are active low indicators. All UART connections are implemented using CMOS technology and have signalling levels of 0V and Vcc. UART configuration parameters, such as Baud rate and packet format, are set using BlueCore4-External software. Page 7 Chongqing JINOU Science and Technology Development Co., Ltd. BTM4504C1H Notes: In order to communicate with the UART at its maximum data rate using a standard PC, an accelerated serial port adapter card is required for the PC. (1) Uses RS232 protocol but voltage levels are 0V to VDD_USB, (requires external RS232 transceiver chip) Parameter Possible Values 1200 Baud (≤2%Error) Minimum Baud Rate 9600 Baud (≤1%Error) Maximum 3.0MBaud (≤1%Error) Flow Control RTS/CTS or None Parity None, Odd or Even Number of Stop Bits 1 or 2 Bits per channel Table 11.7: Possible UART Settings The UART interface is capable of resetting BlueCore4-External upon reception of a break signal. A Break is identified by a continuous logic low (0V) on the UART_RX terminal, as shown in Figure 11.13. If tBRK is longer than the value, defined by the PS Key PSKEY_HOST_IO_UART_RESET_TIMEOUT, (0x1a4), a reset will occur. This feature allows a host to initialise the system to a known state. Also, BlueCore4-External can emit a Break character that may be used to wake the Host. Note: The DFU boot loader must be loaded into the Flash device before the UART or interfaces can be used.This initial flash programming can be done via the SPI. Table 11.3 shows a list of commonly used Baud rates and their associated values the Persistent Store Key PSKEY_UART_BAUD_RATE (0x204). There is no requirement to these standard values. Any Baud rate within the supported range can be set in Persistent Store Key according to the formula in Equation 11.7. USB for use the Baud Rate = PSKEY_UART_BAUD_RATE / 0.004096 Equation 11.7: Baud Rate Baud Rate 1200 2400 4800 9600 19200 38400 57600 76800 115200 230400 460800 921600 1382400 1843200 2764800 Persistent Store Value Hex Dec 0x0005 0x000a 10 0x0014 20 0x0027 39 0x004f 79 0x009d 157 0x00ec 236 0x013b 315 0x01d8 472 0x03b0 944 0x075f 1887 0x0ebf 3775 0x161e 5662 0x1d7e 7550 0x2c3d 11325 Error 1.73% 1.73% 1.73% -0.82% 0.45% -0.18% 0.03% 0.14% 0.03% 0.03% -0.02% 0.00% -0.01% 0.00% 0.00% Page 8 Chongqing JINOU Science and Technology Development Co., Ltd. BTM4504C1H Table 11.8: Standard Baud Rates 8.1 UART Bypass Figure 11.14: UART Bypass Architecture 8.2 UART Configuration While RESET is Active The UART interface for BlueCore4-External while the chip is being held in reset is tri-state. This will allow the user to daisy chain devices onto the physical UART bus. The constraint on this method is that any devices connected to this bus must tri-state when BlueCore4-External reset is de-asserted and the firmware begins to run. 8.3 UART Bypass Mode Alternatively, for devices that do not tri-state the UART bus, the UART bypass mode on BlueCore4-External can be used. The default state of BlueCore4-External after reset is de-asserted, this is for the host UART bus to be connected to the BlueCore4-External UART, thereby allowing communication to BlueCore4-External via the UART. In order to apply the UART bypass mode, a BCCMD command will be issued to BlueCore4-External upon this, it will switch the bypass to PIO[7:4] as shown in Figure 11.14. Once the bypass mode has been invoked, BlueCore4-External will enter the deep sleep state indefinitely. In order to re-establish communication with BlueCore4-External, the chip must be reset so that the default configuration takes affect. It is important for the host to ensure a clean Bluetooth disconnection of any active links before the bypass mode is invoked. Therefore it is not possible to have active Bluetooth links while operating the bypass mode. 8.4 Current Consumption in UART Bypass Mode The current consumption for a device in UART Bypass Mode is equal to the values quoted for a device in standby mode. 9. I/O Parallel Ports Fifteen lines of programmable bi-directional input/outputs (I/O) are provided. PIO[11:8] and PIO[3:0] are powered from Vcc. PIO[7:4] are powered from Vcc. AIO [2:0] are powered from Vref. PIO lines can be configured through software to have either weak or strong pull-ups or pull-downs. All PIO lines are configured as inputs with weak pull-downs at reset. PIO[0] and PIO[1] are normally dedicated to RXEN and TXEN respectively, but they are available for general use. Any of the PIO lines can be configured as interrupt request lines or as wake-up lines from sleep modes. PIO[6] or PIO [2] can be configured as a request line for an external clock source. This is useful when the clock to BlueCore4-External is provided from a Page 9 Chongqing JINOU Science and Technology Development Co., Ltd. BTM4504C1H system application specific integrated circuit (ASIC). BlueCore4-External has three general purpose analogue interface pins, AIO[0], AIO[1] and AIO[2]. These are used to access internal circuitry and control signals. One pin is allocated to decoupling for the on-chip band gap reference voltage, the other three may be configured to provide additional functionality. Auxiliary functions available via these pins include an 8-bit ADC and an 8-bit DAC. Typically the ADC is used for battery voltage measurement. Signals selectable at these pins include the band gap reference voltage and a variety of clock signals; 48, 24, 16, 8MHz and the XTAL clock frequency. When used with analogue signals the voltage range is constrained by the analogue supply voltage (1.8V). When configured to drive out digital level signals (clocks) generated from within the analogue part of the device, the output voltage level is determined by Vref (1.8V). Important Note: CSR cannot guarantee that terminal functions PIOs remain the same. Please refer to the software release note for the implementation of these PIO lines, as they are firmware build specific. 10. RESETB BlueCore4 Module may be reset from several sources: power on reset, a UART break character or via a software configured watchdog timer. The power on reset occurs when the VDD_CORE supply falls below typically 1.5V and is released when VDD_CORE rises above typically 1.6V. At reset the digital I/O pins are set to inputs for bi-directional pins and outputs are tri-stated. The PIOs have weak pull-downs. Following a reset, BlueCore4-External assumes the maximum XTAL_IN frequency, which ensures that the internal clocks run at a safe (low) frequency until BlueCore4-External is configured for the actual XTAL_IN frequency. If no clock is present at XTAL_IN, the oscillator in BlueCore4-External free runs, again at a safe frequency. 10.1 Table 11.15 Pin Name PIO[6:2] UART_TX UART_RX UART_RTS UART_CTS SPI_CSB SPI_CLK SPI_MOSI SPI_MISO AIO[1] Pin States on Reset shows the pin states of BlueCore4-External on reset.
