Disable parity generation and checking.
This bit combination is reserved and should not be used.
This bit combination is reserved and should not be used.
This bit combination is reserved and should not be used.
Enable parity generation and checking with even parity.
Enable parity generation and checking with odd parity.
Enable parity generation and checking with space (always zero) parity.
Enable parity generation and checking with mark (always one) parity.
Normal asynchronous data encoding.
Enable RZI coding (3/16 bit cell IrDA-compliant).
Normal break operation. This option should be selected when address bits are
expected.
Fast break termination. At the end of break, a dummy character is written to the
buffer, and the receiver can start character assembly after one bit time.
Asynchronous clock is 16× data rate.
Asynchronous clock is 8× data rate.
Continue character assembly during break to allow timing the break condition.
Inhibit character assembly during break. One character (all zeros, with framing
error) at start and one character (garbage) at completion.
This bit is ignored in the asynchronous mode.
