Steps to follow when setting up an Asynchronous
Transmission:
1.
Initialize the SPBRG register for the appropriate
baud rate. If a high speed baud rate is desired,
set bit BRGH. (Section 10.1)
2.
Enable the asynchronous serial port by clearing
bit SYNC and setting bit SPEN.
3.
If interrupts are desired, then set enable bit TXIE.
4.
If 9-bit transmission is desired, then set transmit
bit TX9.
5.
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 trans-
mission).
If using interrupts, ensure that GIE and PIE in
the INTCON register are set.
