Personal Area Network
Write 8 bytes into the transmit FIFO (RegUartFifoTx)
Jump to 2) after IrqTxEmpty has been triggered, to write the next 8 bytes if the message is not finished
End of transmission
3.12.9.3
Initialize RegUartFifoBaud and RegUartFifoCtrl with the communication parameters (for example 8-bit word
length, odd parity, 115200 bauds, enable UART reception)
Wait until UartRxDataReady or UartRxFifoFull are set in RegUartFifoRxSta
Check errors in RegUartFifoRxSta
Read data in RegUartFifoRx
Repeat 3) and 4) until the receive FIFO is empty (UartRxDataReady = 0)
Jump to 2)
3.12.9.4
Initialize RegUartFifoBaud and RegUartFifoCtrl with the communication parameters (for example 8-bit word
length, odd parity, 115200 bauds, enable UART reception)
Wait until IrqRxDataReady is triggered
Check errors in RegUartFifoRxSta
Read data in RegUartFifoRx
Repeat 3) and 4) until the receive FIFO is empty (UartRxDataReady = 0)
Jump to 2)
