PEN — Parity Enable Bit
This read/write bit enables the SCI parity function. (See Table 14-5.)
When enabled, the parity function inserts a parity bit in the most
significant bit position. (See Figure 14-3.) Reset clears the PEN bit.
1 = Parity function enabled
0 = Parity function disabled
PTY — Parity Bit
This read/write bit determines whether the SCI generates and checks
for odd parity or even parity. (See Table 14-5.) Reset clears the PTY
bit.
1 = Odd parity
0 = Even parity
NOTE: Changing the PTY bit in the middle of a transmission or reception can
generate a parity error.
