9.3
Table 9.3 shows the INTC register configuration. These registers maintain software interfaces
with the CPU (SH-4A) and are initialized by a power-on reset and a manual reset.
Table 9.3 shows the INTC register configuration. Table 9.4 shows the register states in each
operating mode.

Description
Interrupt request signal input
IRL [7:4] 4-bit level-encoded
interrupt input when ICR0.IRLM1 = 0
IRQ7 to IRQ4 individual interrupt
input when ICR0.IRLM1 = 1
Notifies that an interrupt request has
generated
This pin is asserted even if the CPU
does not accept the interrupt
request, but not asserted when the
interrupt is masked.
Port interrupt request signal input
