No operation. These bits are ignored in the asynchronous mode.
In the HDLC mode, force receiver in flag search mode.
No operation.
In the HDLC mode, transmit an abort pattern.
Enable the receiver input.
Disable the receiver input.
Pin PG7 (Serial Port E) or PG3 (Serial Port F) is used for the receiver input.
Pin PG5 (Serial Port E) or PG1 (Serial Port F) is used for the receiver input.
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.
HDLC mode with external clock. The external clocks are supplied as follows:
HDLC mode with internal clock. The clock is 16× the data rate, and the DPLL is
used to recover the receive clock. If necessary, the clocks are supplied as follows:
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.
Bit 4 is 0—pins PG4 and PG5(Serial Port E); pins PG0 and PG1 (Serial Port F).
Bit 4 is 1—pin PG4 (Serial Port E) and pin PG0 (Serial Port F).
Bit 4 is 0—pins PG4 and PG5(Serial Port E); pins PG0 and PG1 (Serial Port F).
Bit 4 is 1—pin PG4 (Serial Port E) and pin PG0 (Serial Port F).
