(4) Enable the interrupt.
KWUP0-KWUPD) which can be used as a means of terminating a standby mode. For INT0 to INT4,
use the CG block to specify whether they are used to terminate a standby mode and to specify their
active edge or level. For INTB/INTC/INTD/INTE and KWUP0-KWUPD, use the CG block to specify
whether they are used to terminate a standby mode and use INTBCDEST and KWUPSTn,
respectively, to specify their active edge or level. Set the active state for the corresponding interrupt
source to High in the INTC block.
Example: Enable the INT0 interrupt
All interrupt sources other than those which are used to terminate STOP/SLEEP mode are set in the
INTC circuit block.
to INT4 do not require settings in the CG block if they are used as normal interrupts. They still,
however, require level or edge specification in the INTC. If INTB/INTC/INTD/INTE and
KWUP0-KWUPD are used as normal interrupts, specify the active level or edge using
INTBCDEST/KWUPSTn and specify the High level in the INTC. Settings in the CG are not required.
INTRTC always requires settings in both the CG and INTC even if it is used as a normal interrupt.
All interrupt sources other than those which are used to terminate a standby mode are set in the
INTC circuit block.
