Valid only when “can be stopped by software” is selected for internal oscillator by the option byte.
Do not set MCC = 1 or MSTOP = 1 during high-speed system clock operation (even if MCC = 1 or
MSTOP = 1 is set, the high-speed system clock oscillation does not stop).
Do not set MCC = 1 during internal oscillation clock operation (even if MCC = 1 is set, the high-speed
system clock oscillation does not stop). To stop high-speed system clock oscillation during internal
oscillation clock operation, use MSTOP.
Shifting to subsystem clock operation mode must be performed from the high-speed system clock
operation mode. From subsystem clock operation mode, only high-speed system clock operation mode
can be shifted to.
Do not set MCM0 = 0 (shifting to internal oscillation clock operation) during subsystem clock operation.
Do not set MSTOP = 1 during subsystem clock operation (even if MSTOP = 1 is set, high-speed system
clock oscillation does not stop). To stop high-speed system clock oscillation during subsystem clock
operation, use MCC.
