Serial Communications Interface
12.9.2 SCI Control Register 2
Technical Data
232
NOTE:
PTY — Parity Bit
Changing the PTY bit in the middle of a transmission or reception can
generate a parity error.
SCI control register 2:
This read/write bit determines whether the SCI generates and checks
for odd parity or even parity. (See
bit.
