Section 12 Serial Communication Interface
12.2.5
SMR is an 8-bit register that specifies the SCI's serial communication format and selects the clock
source for the baud rate generator.
The CPU can always read and write SMR. SMR is initialized to H'00 by a reset and in standby
mode.
Bit 7—Communication Mode (C/
normal serial communication interface and for the smart card interface. Its function is switched
with the SMIF bit in SCMR.
