(Transmit buffer
TRISB<1> and TRISB<2> should both be set to
‘1’ to configure the RB1/RX/DT and RB2/TX/CK
pins as inputs. Output drive, when required, is
controlled by the peripheral circuitry.
Initialize the SPBRG register for the appropriate
baud rate. If a high-speed baud rate is desired,
set bit BRGH. (Section 12.1 “USART Baud
Rate Generator (BRG)”).
Enable the asynchronous serial port by clearing
bit SYNC and setting bit SPEN.
If interrupts are desired, then set enable bit
TXIE.
If 9-bit transmission is desired, then set transmit
bit TX9.
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).
