  • Page 12: Uart Interface

    CSR8811 UART interface provides a simple mechanism for communicating with other serial devices using the RS-232 protocol. The above figure shows the 4 signals that implement the UART function. When BT830 is connected to another digital device, UART_RX and UART_TX transfer data between the 2 devices. The remaining 2 signals, UART_CTS and UART_RTS, implement RS232 hardware flow control where both are active low indicators.
  • Page 13 Long Frame Sync is the name given to a clocking format that controls the transfer of PCM data words or samples. In Long Frame Sync, the rising edge of PCM_SYNC indicates the start of the PCM word. When the BT830 is configured as PCM master, generating PCM_SYNC and PCM_CLK, then PCM_SYNC is eight bits long.
  • Page 14 Figure 5: Short Frame Sync (Shown with 16-bit Sample) As with Long Frame Sync, BT830 samples PCM_IN on the falling edge of PCM_CLK and transmits PCM_OUT on the rising edge. PCM_OUT is configurable as high impedance on the falling edge of PCM_CLK in the LSB position or on the rising edge.
