14.8.4
The transmission and reception software can be driven by interruption or by polling the status bits.
Interrupt driven reception: each time an Irq_uart_Rx interrupt is generated, a new word is available in RegUartRx.
The register has to be read before a new word is received.
Interrupt driven transmission: each time the contents of RegUartTx is transferred to the transmission shift register,
an Irq_uart_Tx interrupt is generated. A new word can then be written to RegUartTx.
Reception driven by polling: the UartRxFull bit is to be read and checked. When it is 1, the RegUartRx register
contains new data and has to be read before a new word is received.
Transmission driven by polling: the UartTxFull bit is to read and checked. When it is 0, the RegUartTx register is
empty and a new word can be written to it.
14.9 Software hints
Example of program for a transmission with polling:
1. The RegUartCmd register and the RegUartCtrl register are initialized (for example: 8 bit word length, odd
2. Write a byte to RegUartTx.
3. Wait untill the UartTxFull bit in RegUartTxSta register equals 0.
4. Jump to 2 to writing the next byte if the message is not finished.
5. End of transmission.
Example of program for a transmission with interrupt:
1. The RegUartCmd register and the RegUartCtrl register are initialized (for example: 8 bit word length, odd
2. Write a byte to RegUartTx.
3. After an interrupt and if the message is not finished, jump to 2
4. End of transmission.
