(4) Internal oscillation mode register (RCM)
122
This register sets the operation mode of internal oscillator.
RCM can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets this register to 80H
Address: FFA0H

RCM
Notes 1. The value of this register is 00H immediately after a reset release but automatically
Caution When setting RSTOP to 1, be sure to confirm that the CPU operates with a clock
