10. Interrupt Controller (INTC)
Table 10.16 shows response time. The response time is the time until when the interrupt request
signal from the INTC to the CPU is negated. In this case, suppose that the setting values of the
following registers, INTMSK0, INTMSK1, INTMSK2, INT2MSKR, and INT2GPIC, are changed
from the interrupt enable state to the interrupt disable state.

The IRL interrupt source that has been already retained inside cannot cancel the
interrupt request signal to the CPU even if the IRL interrupt source is masked.
