12.9.6 SCI Data Register
MC68HC908JB16
Freescale Semiconductor
NOTE:
—
Rev. 1.1
Address:
The SCI data register (SCDR) is the buffer between the internal data bus
and the receive and transmit shift registers.
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 SCI data register accesses the read-only received data
bits, R7:R0. Writing to the SCI data register writes the data to be
transmitted, T7:T0. Reset has no effect on the SCI data register.
