WORD 1
Transmit Shift Reg
TXIE
Initialize the SPBRG register for the appropriate baud rate. If a high speed baud rate is
desired, set the BRGH bit. (Subsection
Enable the asynchronous serial port by clearing the SYNC bit and setting the SPEN bit.
If interrupts are desired, then set the TXIE, GIE and PEIE bits.
If 9-bit transmission is desired, then set the TX9 bit.
Enable the transmission by setting the TXEN bit, which will also set the TXIF bit.
If 9-bit transmission is selected, the ninth bit should be loaded in the TX9D bit.
Load data to the TXREG register (starts transmission).
