152 / 1075 page  Section 5 Interrupt Controller Rev. 3.00 Jan 18, 2006 page 124 of 1044 REJ09B0280-0300 5.5 Interrupt Operation 5.5.1 Interrupt Control Modes and Interrupt Operation Interrupt operations in the H8S/2169 or H8S/2149 differ depending on the interrupt control mode. NMI and address break 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 ICR, and the masking state indicated by the I and UI bits in the CPU’s CCR. Table 5.5 Interrupt Control Modes SYSCR Interrupt Control Mode INTM1 INTM0 Priority Setting Register Interrupt Mask Bits Description 0 0 0 ICR I Interrupt mask control is performed by the I bit Priority can be set with ICR 1 1 ICR I, UI 3-level interrupt mask control is performed by the I and UI bits Priority can be set with ICR Figure 5.7 shows a block diagram of the priority decision circuit. |
