(2) Internal oscillation mode register (RCM)
(3) CPU operation clock status register (CCLS)
Cautions 1. The internal oscillator cannot be stopped while the CPU is operating on the internal
The RCM register is an 8-bit register that sets the operation mode of the internal oscillator.
This register can be read or written in 8-bit or 1-bit units.
Reset sets this register to 00H.
The CCLS register indicates the status of the CPU operation clock.
This register is read-only, in 8-bit or 1-bit units.
Reset sets this register to 00H.
Note If WDT overflow occurs during oscillation stabilization after a reset is released, the CCLSF bit is set
2. The internal oscillator oscillates if the CCLS.CCLSF bit is set to 1 (when WDT overflow
