Section 28 Power-Down Modes
(2)
Deep standby mode is canceled by interrupts (NMI or an IRQ assigned to PE11 to PE4) or a reset
(manual reset or power-on reset). When canceling the mode by the interrupt NMI or IRQ, a
power-on reset exception handling is executed instead of an interrupt exception handling. When
canceling the mode by manual reset, the same handling is executed.
Figure 28.3 shows the flowchart of canceling deep standby mode.
