Note 1: Interrupt level 0 indicates that the corresponding interrupt is disabled.
Note 2: Only a rising edge can be used for INTRTC.

When used to terminate a standby mode, the interrupt source active state
must be set to High in the INTC block. The active state of these interrupts
must be selected in the CG. However, when these interrupts are not used to
terminate a standby mode, their active state must be selected in the INTC
block. In both cases, Low level, High level, falling edge and rising edge are all
acceptable.
The interrupt source active state must always be set to High in the INTC
block. When these interrupts are used to terminate a standby mode, the
interrupt source active state must also be set to High in the CG. The active
state of these interrupts must be selected in INTnST. However, when these
interrupts are not used to terminate a standby mode, settings in the CG are
not necessary. In both cases, Low level, High level, falling edge and rising
edge are all acceptable.

Low level, High level, falling edge and rising edge are all acceptable in the
INTC.
Falling edge
Rising edge
: Select falling edge for INT0
: Clear interrupt request for INT0
: Enable request input for INT0
: Select High level for INT0
: Clear interrupt request for INT0
: Set interrupt level to 5
: Disable interrupt for INT0
: Clear interrupt request for INT0
: Disable request input for INT0
: Clear interrupt request for INT0
