Section 13 Serial Communication Interface
13.2.6
SCR enables the SCI transmitter and receiver, enables or disables serial clock output in
asynchronous mode, enables or disables interrupts, and selects the transmit/receive clock source.
Bit
Initial value
Read/Write
The CPU can always read and write SCR. SCR is initialized to H'00 by a reset and in standby
mode.
