IDLE instruction D
Sub Stop mode Main oscillator is stopped by
SCMOD.3.
Sub oscillator runs.
System clock is the sub
oscillation clock.
Setting SCMOD.2 to “1”
This mode can be released
only by an external reset.
E
Main/Sub Stop mode Main oscillator runs.
Sub oscillator is stopped by
SCMOD.2.
System clock is the main
oscillation clock.
STOP instruction:
This mode can be released
by an interrupt and reset.
E
NOTE:The current consumption is: A > B > C > D > E.
