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 request generated by execution of a
SLEEP instruction, this function is included in IRR1, IRR2, IENR1, and IENR2.
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. These interrupts can be masked by
writing 0 to clear the corresponding enable bit.
