5.4 Interrupt Operation
5.4.1 Interrupt Control Modes and Interrupt Operation
Interrupt operations in the H8S/2357 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.
