(Program execution state)
Note 1. If an interrupt is accepted while entering low power consumption mode, the transition to the program stop state is exited
and the interrupt exception handling is executed.
Note 2. “Interrupts” here indicates an external pin interrupt (the NMI or IRQ0 to IRQ5) or any of peripheral interrupts (the IWDT and
voltage monitoring interrupts).
Note 3. The LOCO is the clock source following a transition from the reset state to normal mode.
Note 4. Makes a transition from sleep mode, deep sleep mode, or software standby mode to normal operating mode by an
interrupt.
For deep sleep mode and software standby mode, the clock source after exiting is the same as that of the clock before
entering software standby mode.
Transition to the reset state is made at any state instantly after a RES# pin reset, power on reset, voltage monitoring reset, IWDT
reset, or software reset is generated.
