14.8 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 until the UartTxFull bit in RegUartTxSta register equals 0.
4. Jump to 2 to write 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.
Example of program for a reception with polling:
1. The RegUartCmd register and the RegUartCtrl register are initialized (for example: 8 bit word length, odd
2. Wait until the UartRxFull bit in the RegUartRxSta register equals 1.
3. Read the RegUartRxSta and check if there is no error.
4. Read data in RegUartRx.
5. If data is not equal to End-Of-Line, then jump to 2.
6. End of reception.
Example of program for a reception with interrupt:
1. The RegUartCmd register and the RegUartCtrl register are initialized (for example: 8 bit word length, odd
2. When there is an interrupt, jump to 3
3. Read RegUartRxSta and check if there is no error.
4. Read data in RegUartRx.
5. If data is not equal to End-Of-Line, then jump to 2.
6. End of reception.
