Clock Master:
1 - Transmitter and/or receiver use 1x clock generated by
the internal transmitter.
0 - Transmitter and/or receiver use 1x clock generated
externally.
Transmit Clock Mode.
1 - Generate 1x clock when in synchronous HDLC mode
using NRZ encoding.
0 - Do not generate clock.
This bit has no effect unless TXENC is clear and
synchronous HDLC is enabled.
Receive Clock Mode.
1 - Use external 1x clock when in synchronous HDLC
mode using NRZ encoding.
0 - Do not use external clock.
This bit has no effect unless RXENC is clear and
synchronous HDLC is enabled.
Transmit Encoding method.
1 - Use Manchester bit encoding.
0 - Use NRZ bit encoding.
This bit has no effect unless synchronous HDLC is
enabled
Receive Encoding method.
1 - Use Manchester bit encoding.
0 - Use NRZ bit encoding.
This bit has no effect unless synchronous HDLC is
enabled.
Synchronous / Asynchronous HDLC Enable.
0 - Select asynchronous HDLC for TX and RX.
1 - Select synchronous HDLC for TX and RX.
Transmit Frame Complete Interrupt Enable.
0 - TFC interrupt will not occur.
1 - TFC interrupt will occur whenever TFC bit is set.
Transmit Frame Abort Interrupt Enable.
0 - TAB interrupt will not occur.
1 - TAB interrupt will occur whenever TAB bit is set.
Receive Frame Complete Interrupt Enable.
0 - RFC interrupt will not occur.
1 - RFC interrupt will occur whenever RAB bit or EOF bit is
set.
