Section 3 Exception Handling
3.4.2
Each on-chip peripheral module has a flag to show the interrupt request status and the enable bit to
enable or disable the interrupt. For direct transfer interrupt requests generated by execution of a
SLEEP instruction, this function is included in IRR1 and IENR1.
When an on-chip peripheral module requests an interrupt, the corresponding interrupt request
status flag is set to 1, requesting the CPU of an interrupt. When this interrupt is accepted, the I bit
is set to 1 in CCR. These interrupts can be masked by writing 0 to clear the corresponding enable
bit.
