Revision (See Manual for Details)
Description amended
…After the elapse of the time set in the clock select bits
(CKS[2:0]) in the watchdog timer control/status register
(WTCSR) of the WDT before the transition to software
standby mode, the WDT overflow occurs. Since this overflow
indicates that the clock has been stabilized, the clock pulse
will be supplied to the entire chip after this overflow. Software
standby mode is thus cleared and NMI interrupt exception
handling (IRQ interrupt exception handling in case of IRRQ)
is started. If the priority level of the generated interrupt is
equal to or lower than the interrupt mask level specified in the
status register (SR) of the CPU, the interrupt request is not
accepted and software standby mode is not canceled.
Description amended
When the falling edge or rising edge of the NMI pin (selected
by the NMI edge select bit (NMIE) in interrupt control register
0 (ICR0) of the interrupt controller (INTC)) or the falling edge
or rising edge of an IRQ pin (IRQ7 to IRQ0 assigned to PE11
to PE4) (selected by the IRQn sense select bits (IRQn1S and
IRQn0S) in interrupt control register 1 (ICR1) of the interrupt
controller (INTC)) is detected, clock oscillation is started after
the wait time for the oscillation settling time. After the
oscillation settling time has elapsed, deep standby mode is
cancelled and the power-on reset exception handling is
executed. If the priority level of the generated interrupt is
equal to or lower than the interrupt mask level specified in the
status register (SR) of the CPU, the interrupt request is not
accepted and deep standby mode is not canceled.
… (The same applies to the IRQ pin.)
In addition, the pin levels of the NMI pin and all interrupt pins
(IRQ) selected to cancel deep standby mode (by settings in
the deep standby mode cancelation source select register)
should be as follows during the transition to deep standby
mode, regardless of whether or not those pins are actually
used to cancel deep standby mode:
Canceling by an interrupt
Canceling by an interrupt
⎯ Pins set to cancel deep standby mode at their rising
⎯ Pins set to cancel deep standby mode at their falling
edge should be low during the transition.
edge should be high during the transition.
