What are the steps for initialising the UART transmitter and receiver in the HT48RU80?
Answer Transmitter Initialisation Steps: 1. Setup the BN0, PRT, PREN and STOPS to determine the data length, parity type and stop bit length. 2. Setup the BRG register to choose the baud rate. 3. Set the TXEN bit to enable the UART transmit function. 4. Read the USR register, and place the data waiting to be transmitted into the TXR register. This step will clear the TXIF flag. 5. If more data is to be transmitted only the previous step needs to be repeated. Receiver Initialisation Steps: 1. Setup the BN0, PRT, PREN and STOPS to determine the data length, parity type and stop bit length. 2. Setup the BRG register to choose the baud rate. 3. Set the RXEN bit to enable the UART receive function. Now the UART will start to examine the first data bit. 4. After the data has been properly read, read the USR register. This step will clear the RXIF flag. 5. Read the RXR register to obtain the data .
