Note 1:
Name
Initialize the SPBRG register for the appropriate
baud rate. If a high-speed baud rate is desired,
set bit BRGH (Section 18.2 “USART Baud
Rate Generator (BRG)”).
Enable the asynchronous serial port by clearing
bit, SYNC, and setting bit, SPEN.
If interrupts are desired, set enable bit, TXIE.
If 9-bit transmission is desired, set Transmit bit,
TX9. Can be used as address/data bit.

The PSPIF, PSPIE and PSPIP bits are reserved on the PIC18F2X20 devices; always maintain these bits clear.
This timing diagram shows three words appearing on the RX input. The RCREG (Receive Buffer) is read after the third word,
causing the OERR (Overrun) bit to be set.

Enable the transmission by setting bit, TXEN,
which will also set bit, TXIF.
If 9-bit transmission is selected, the ninth bit
should be loaded in bit, TX9D.
Load data to the TXREG register (starts
transmission).
If using interrupts, ensure that the GIE and PEIE
bits in the INTCON register (INTCON<7:6>) are
set.
