Section 5 Interrupt Controller
5.2.2
The ICR registers are three 8-bit readable/writable registers that set the interrupt control level for
interrupts other than NMI and address break.
The correspondence between ICR settings and interrupt sources is shown in table 5.3.
The ICR registers are initialized to H'00 by a reset and in hardware standby mode.
Bit n—Interrupt Control Level (ICRn): Sets the control level for the corresponding interrupt
source.
