Section 28 Power-Down Modes
(3) Note on Release from Software Standby Mode
Release from software standby mode is triggered by interrupts (NMI and IRQ) or resets (manual
reset and power-on reset). If, however, a SLEEP instruction and an interrupt other than NMI and
IRQ are generated at the same time, cancellation of software standby mode may occur due to
acceptance of the interrupt.
When initiating a transition to software standby mode, make settings so that interrupts are not
generated before execution of the SLEEP instruction.
