13.11.6 SCI Data Register
MC68HC908LJ24/LK24 — Rev. 2.1
Freescale Semiconductor
NOTE:
Address:
Infrared Serial Communications Interface Module (IRSCI)
The SCI data register is the buffer between the internal data bus and the
receive and transmit shift registers. Reset has no effect on data in the
SCI data register.
R7/T7–R0/T0 — Receive/Transmit Data Bits
Do not use read/modify/write instructions on the SCI data register.
Reset:
Read:
Write:
Reading the SCDR accesses the read-only received data bits,
R7–R0. Writing to the SCDR writes the data to be transmitted, T7–T0.
Reset has no effect on the SCDR.
