mode, the parity bit can be added to the transmitted character, and the receiver can
perform a parity check on incoming data. Parity can be enabled and disabled by
programming the SC0CR<PE> bit. When <PE> is set to 1 to enable parity, the
SC0CR<EVEN> bit selects even or odd parity.
Example: Receiving data with odd parity in 8-bit UART mode
X: Don’t care 、− : No change
Acc ← SC0CR AND 00011100
if Acc ← 0 then ERROR
Acc ← SC0BUF
Setting the SC0MOD0<SM1:0> field to 10 puts the SIO0 in 8-bit UART mode. In this
