See Chapter 12 “RegulatoryStatements”.7.2 UART InterfacePER1220 Universal Asynchronous Receiver Transmitter (UART) interface provides a simplemechanism for communicating with other serial devices using the RS232 Standard (1).UART_TXUART_RXUART_RTSUART_CTSPER1220Figure 6: Universal Asynchronous Receiver TransmitterFour signals are used to implement the UART Function as shown in figure 6. When PER1220 isconnected 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 hardwareflow control. Where both are active low indicators. All UART connections are implemented usingCMOS technology and have signalling levels of 0 V and 3.3 V.UART configuration parameters, such baud rate and packet format, can optionally setNote:(1) Uses RS232 Protocol, but voltage levels are 0 V to 3.3 V (requires external RS232 transceiver IC)Parameter Possible Values1200 Baud (<= 2% Error)Minimum9600 Baud (<= 1% Error)Baud RateMaximum 1.5 Mbaud (<= 1% Error)Flow Control RTS/CTS or noneParity None, odd, evenStop Bit 1 or 2Bits per channel 8

PER1220 Data Book Page 15/21Copyright  Prettl Elektronik Radeberg GmbH. All rights reserved.The UART interface is cabable of resetting the PER1220 upon reception of a break signal (see figure8). A break is identified by a continuos logic low on the RX terminal, as shown in figure. If tbrk is longerthan the value, defined as manufacture setting, a reset will occur.tbrkFigure 8: UART Break Signal7.3 USB InterfacePER1220 contain a full speed (12 Mbit/s) USB interface, capable of driving a USB cable directly. Noexternal USB transceiver is required. The device operates as a USB peripheral, responding torequests from a master host controller such a PC. Both the OHCI and the UHCI standards aresupported. The set of USB endpoints implemented behave as a specified in the USB section of theBluetooth Specification V1.2, part H2.As USB is a master-slave oriented system, PER1220 only supports USB slave operation.For more details, please contact PRETTL® Support.7.4 Serial Peripheral InterfacePER1220 holds the firmware and the persistent store in a flash. It can be read/write by the SPI.Normally, this will be done by PRETTL®. Ask for more details7.5 PCMPulse Code Modulation (PCM) is the standard method used to digitise human voice patterns fortransmission over digital communication channels. Through it’s PCM interface, PER1220 hashardware support for continual transmission and reception of PCM data, thus reducing processoroverhead for wireless headset applications. PER1220 offers a bi-directional digital audio interface thatroutes directly into the Baseband layer to the on-chip firmware. It does not pass through the HCIprotocol layer.Hardware on PER1220 allows the data to be sent and received from a SCO connection.Up to three SCO connections can be supported by the PCM interface at any one time. (1)PER1220 can operate as the PCM interface Master generating an output clock of 128, 256 or 512kHz. When configured as PCM interface slave it can operate with an input clock up to 2048 kHz.PER1220 is compatible with a variety of clock formats, including Long Frame Sync, Short Frame Syncand GCI timing environments.
