CONFIDENTIAL Page 9 Revision 0.1 KwikBlue4-1 Bluetooth® Class 1 BC04 Module Manual 3.3 RESET Sequence RESET is asserted by module itself, the external reset circuit is not required. 3.4 UART (Universal Asynchronous Receiver Transmitter) UART_TxD, UART_RxD, UART_RTS, UART_CTS form a conventional asynchronous data serial port. The interface is designed to operate correctly when connected to other UART devices such as the NS16550A. The signaling levels are 0V and VCC. The interface is programmable over a variety of bit rates; none, even or odd parity; one or two stop bits and hardware flow control on or off. The default condition on power-up is pre-assigned in the Flash memory. The maximum UART data rate is 1.3824 Mbps. Two-way hardware flow control is implemented by UART_RTS and UART_CTS. UART_RTS is an output and is active low. UART_CTS is an input and is active low. These signals operate according to normal industry convention.

CONFIDENTIAL Page 11 Revision 0.1 KwikBlue4-1 Bluetooth® Class 1 BC04 Module Manual simultaneously 3.5.4 Limitations 1) Power Specific Limitations: today, the host controller of USB capable machines resides inside a chip known as PIIX4. Because of the design, the USB host controller will not receive power while the system is in S3 or S4. This means that a USB wakeup can only occur when the system is in S1 or S2. Another issue with the USB host controller is that, while a device is attached, it continually snoops memory to see if there is any work that needs to be done. The frequency that it checks memory is 1ms. This prevents the processor from dropping into a low power state known as C3. Because the notebook processor is not able to enter the C3 state, SIGNIFICANT power loss will occur. This is a real issue for business users – as a typical business user will spend almost 90% of their time in the C3 state. 2) Other Limitations: data corruption may occur across isochronous endpoints. Endpoints one and two may suffer from data corruption. USB provides 16-CRC on all data transfers. The USB has a bit error rate of 10 –13 .

CONFIDENTIAL Page 12 Revision 0.1 KwikBlue4-1 Bluetooth® Class 1 BC04 Module Manual 3.6 PCM 3.6.1 Features The Bluetooth module implements an audio transcoder to translate between A-law, µ-law and linear voice data from the host and A-l a w, µ-law and CVSD voice data over the air. Voice interpolation for lost packets is also included. PCM_OUT, PCM_IN, PCM_CLK and PCM_SYNC carry up to three bi-directional channels of voice data, each at 8 ks/s. The PCM samples can be 8-bit A-law, 8-bit µ-law, 13-bit linear or 16-bit linear format. The PCM_CLK and PCM_SYNC pins can be configured as inputs or outputs, depending on whether the Bluetooth module is the master or slave of the PCM interface. The PCM_SYNC operates at a fixed clock frequency of 8 KHz. When PCM_SYNC is operated as an output (master mode) a clock frequency of 8 KHz is generated from this pin. When operated as an input (slave mode) 8 KHz must be applied to this pin. PCM_CLK operates at a fixed clock frequency of 256 KHz. When PCM_CLK is operated as an output (master mode) a clock frequency of 256 KHz is generated from this pin. When operated as an input (slave mode) 256 KHz must be input on this pin. When used with the Motorola MC145483 PCM or compatible devices, bits 1 to 13 of the PCM_OUT data carry the current output sample value. Bits 14 to 16 carry a three-bit signal level value and these “level bits” vary the level of the audio signal output from the PCM device. 3.6.2 Recommended Codec IC The Bluetooth module can be interfaced directly to the following PCM audio chips: OKI MSM7705 four channel µ/A-law codec Motorola MC145481 8-bit µ/A-law codec Motorola MC145483SD 13-bit linear codec Mitel MT93LI6 Echo canceling codec PCM_CLK mclk risel synclk clksyn pw l Hdsyn fall 10 11 12 13 14 pw h PCM_SYNC Dtmsb Dtmsb Dt13 Dtclk PCM_OUT D1 D2 D3 D4 D5 D6 D7 D8 D9 D11 D12 D13 mclk synclk PCM_CLK D10 pw l clksyn Hdsyn 10 11 12 13 D11 D12 D13 14 pw h PCM_SYNC Dinvl Dval PCM_IN D1 D2 D3 D4 D5 D6 D7 D8 D9 D10 Figure 1: PCM Bus Transfer Definition June 21, 2005 Document#: Copyright © 2004-2005 Socket Communications, Inc.
