Section 25 Power-Down Modes
(2)
Deep standby mode is canceled by interrupts (NMI or IRQ) or a reset (manual reset or power-on
reset). However, IRQ is canceled only by PE7 to PE4 and PC25 to PC22. To cancel deep standby
mode by interrupt NMI or IRQ, a power-on reset exception handling instead of an interrupt
exception handling is executed. In the same way, a power-on reset exception handling is executed
by a power-on reset. Figure 25.3 shows the flowchart of canceling deep standby mode.
