No operation. These bits are ignored in the asynchronous mode.
In clocked serial mode, start a byte receive operation.
In clocked serial mode, start a byte transmit operation.
In clocked serial mode, start a byte transmit operation and a byte receive
operation simultaneously.
Enable the receiver input.
Disable the receiver input.
This bit is ignored.
Asynchronous mode with 8 bits per character.
Asynchronous mode with 7 bits per character. In this mode the most significant
bit of a byte is ignored for transmit, and is always zero in receive data.
Clocked serial mode with external clock.
Serial Port C clock is on Parallel Port F pin 1
Serial Port D clock is on Parallel Port F pin 0
Clocked serial mode with internal clock.
Serial Port C clock is on Parallel Port F pin 1
Serial Port D clock is on Parallel Port F pin 0
The serial port interrupt is disabled.
The serial port uses Interrupt Priority 1.
The serial port uses Interrupt Priority 2.
The serial port uses Interrupt Priority 3.
