2 Stop bit length:
1: 1.5 stop bits for 5 bit WORD length
1: 2 stop bits for 6, 7, and 8 bit WORD length
0: 1 stop bit for any serial character WORD
length 0 LPC: r/w
3 Parity enable/disable
When bit 3 is set, a parity bit is generated in
transmitted data between the last data
WORD bit and the first stop bit. In received
data, if bit 3 is set, parity is checked. When
bit 3 is cleared, no parity is generated or
checked:
1: Parity enabled
0: Parity disabled 0 LPC: r/w
4 Parity even/odd
When parity is enabled and bit 4 is set, even
parity (an even number of logic ones in the
data and parity bits) is selected. When parity
is disabled and bit 4 is cleared, odd parity (an
odd number of logic ones) is selected:
1: Even parity
0: Odd parity 0 LPC: r/w
5 Stick parity
When bits 3, 4, and 5 are set, the parity bit is
transmitted and checked as cleared. When
bits 3 and 5 are set and bit 4 is cleared, the
parity bit is transmitted and checked as set. If
bit 5 is cleared, stick parity is disabled:
1: Stick parity enabled
0: Stick parity disabled 0 LPC: r/w
