Infrared Serial Communications Interface Module (IRSCI)
I/O Registers
PTY â Parity Bit
This read/write bit determines whether the SCI generates and checks
for odd parity or even parity. (See Table 13-6.) 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.
