As with other maskable interrupts, the interrupts of timer RC, timer RD (timer RD0), timer RD (timer RD1), timer
RG, the synchronous serial communication unit, the I
combination of the I flag, IR bit, bits ILVL0 to ILVL2, and IPL. However, since each interrupt source is generated
by a combination of multiple interrupt request sources, the following differences from other maskable interrupts
apply:
•
•
•
•
•
Refer to chapters of the individual peripheral functions (19. Timer RC, 20. Timer RD, 22. Timer RG, 26.
Synchronous Serial Communication Unit (SSU), 27. I
register and enable register.
For the interrupt control register, refer to 11.3 Interrupt Control.
When bits in the enable register are set to 1 and the corresponding bits in the status register are set to 1 (interrupt
enabled), the IR bit in the interrupt control register is set to 1 (interrupt requested).
When either bits in the status register or the corresponding bits in the enable register, or both are set to 0, the IR
bit is set to 0 (no interrupt requested).
That is, even if the interrupt is not acknowledged after the IR bit is set to 1, the interrupt request will not be
retained.
Also, the IR bit is not set to 0 even if 0 is written to this bit.
Individual bits in the status register are not automatically set to 0 even if the interrupt is acknowledged.
The IR bit is also not automatically set to 0 when the interrupt is acknowledged.
Set individual bits in the status register to 0 in the interrupt routine. Refer to the status register figure for how to
set individual bits in the status register to 0.
When multiple bits in the enable register are set to 1 and other request sources are generated after the IR bit is set
to 1, the IR bit remains 1.
When multiple bits in the enable register are set to 1, use the status register to determine which request source
causes an interrupt.
