16.9.6 SCI Data Register
MC68HC908SR12•MC68HC08SR12 — Rev. 5.0
Freescale Semiconductor
NOTE:
Address:
The SCI data register (SCDR) 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 SCI data register (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.
