No operation. These bits are ignored in the asynch 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.
Parallel Port C is used for input.
Parallel Port D is used for input.
Disable the receiver input.
Asynch mode with 8 bits per character.
Asynch 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 A clock is on Parallel Port B pin 1
Serial Port B clock is on Parallel Port B pin 0
Clocked serial mode with internal clock.
Serial Port A clock is on Parallel Port B pin 1
Serial Port B clock is on Parallel Port B pin 0
The serial port interrupt is disabled.
The serial port uses Interrupt Priority 1.
The serial port uses Interrupt Priority 2.
