As interrupt request flags IRQ7F to IRQ0F are set when the setting condition is met, regardless of
the IER setting, only the necessary flags should be referenced.
Interrupts KIN15 to KIN0 and WUE7 to WUE0: Interrupts KIN15 to KIN0 and WUE7 to
WUE0 are requested by input signals at pins KIN15 to KIN0 and WUE7 to WUE0. When any of
pins KIN15 to KIN0 or WUE7 to WUE0 are used as key-sense inputs or wakeup events, the
corresponding KMIMR or WUEMR bits should be cleared to 0 to enable those key-sense input
interrupts or wakeup event interrupts. The remaining unused key-sense input KMIMR bits and
WUEMR bits should be set to 1 to disable those interrupts. Interrupts WUE7 to WUE0 and KIN15
to KIN8 correspond to the IRQ7 interrupt, and interrupts KIN7 to KIN0 correspond to the IRQ6
interrupt. Interrupt request generation pin conditions, interrupt request enabling, interrupt control
level setting, and interrupt request status indications, are all in accordance with the IRQ7 and
IRQ6 interrupt settings.
When pins KIN7 to KIN0, KIN15 to KIN8, or WUE7 to WUE0 are used as key-sense interrupt or
wakeup event interrupt input pins, either low-level sensing or falling-edge sensing must be
designated as the interrupt sense condition for the corresponding interrupt source (IRQ6 or IRQ7).
5.3.2
There are 48 sources for internal interrupts from on-chip supporting modules, plus one software
interrupt source (address break).
For each on-chip supporting module there are flags that indicate the interrupt request status,
and enable bits that select enabling or disabling of these interrupts. If any one of these is set to
1, an interrupt request is issued to the interrupt controller.
The interrupt control level can be set by means of ICR.
The DTC can be activated by an FRT, TMR, SCI, or other interrupt request. When the DTC is
activated by an interrupt, the interrupt control mode and interrupt mask bits have no effect.
