13.11.2 SCI Control Register 2
MC68HC908LJ24/LK24 — Rev. 2.1
Freescale Semiconductor
NOTE:
Infrared Serial Communications Interface Module (IRSCI)
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
