Interrupt Operation

5.4.1

Interrupt Control Modes and Interrupt Operation

Interrupt operations in the H8S/2350 Group differ depending on the interrupt control mode.

NMI interrupts are accepted at all times except in the reset state and the hardware standby state. In

the case of IRQ interrupts and on-chip supporting module interrupts, an enable bit is provided for

each interrupt. Clearing an enable bit to 0 disables the corresponding interrupt request. Interrupt

sources for which the enable bits are set to 1 are controlled by the interrupt controller.

Table 5.5 shows the interrupt control modes.

The interrupt controller performs interrupt control according to the interrupt control mode set by

the INTM1 and INTM0 bits in SYSCR, the priorities set in IPR, and the masking state indicated

by the I and UI bits in the CPU’s CCR, and bits I2 to I0 in EXR.
