NRZ data encoding for HDLC receiver and transmitter.
NRZI data encoding for HDLC receiver and transmitter.
Biphase-level (Manchester) data encoding for HDLC receiver and transmitter.
Biphase-space data encoding for HDLC receiver and transmitter.
Biphase-mark data encoding for HDLC receiver and transmitter.
Normal HDLC data encoding.
Enable RZI coding (¼ bit cell IrDA-compliant). This mode can only be used
with an internal clock and NRZ data encoding.
Idle line condition is flags.
Idle line condition is all ones.
Transmit flag on underrun.
Transmit abort on underrun.
These bits are ignored in the HDLC mode and are set to zeros.
Time constant for the Timer A counter. This time constant will take effect the
next time that the Timer A counter counts down to zero. The timer counts
modulo n + 1, where n is the programmed time constant.
