Word Length Select
“00”: word length = 5
“01”: word length = 6
“10”: word length = 7
“11”: word length = 8
Stop Bit Length
‘0’: Stop bit length = 1
‘1’: Stop bit length = 1.5 when WLS[1..0]=”00”, else Stop bit length = 2
Parity Selection
“xx0”: No Parity
“001”: odd Parity
“011”: even Parity
“101”: Stick Parity 1
“111”: Stick parity 0
Set Break
When enable the break control bit causes a break condition to be transmitted (SOUT is
forced to a logic 0 state). This condition exists until disabled by resetting this bit to
logic 0.
‘0’: disable break; ‘1’: enable break
Baud Rate Generator
‘0’: disable baud rate clock generator
‘1’: enable baud rate clock generator
