Description
Direct Transfer Interrupt Request Flag
[Setting condition]
When a direct transfer is made by executing a SLEEP
instruction while DTON in SYSCR2 is set to 1.
[Clearing condition]
When IRRDT is cleared by writing 0
Timer A Interrupt Request Flag
[Setting condition]
When the timer A counter value overflows
[Clearing condition]
When IRRTA is cleared by writing 0
Reserved
These bits are always read as 1.
IRQ3 Interrupt Request Flag

IRQ2 Interrupt Request Flag
[Setting condition]
When IRQ2 pin is designated for interrupt input and
the designated signal edge is detected.
[Clearing condition]
When IRRI2 is cleared by writing 0
IRQ1 Interrupt Request Flag
[Setting condition]
When IRQ1 pin is designated for interrupt input and
the designated signal edge is detected.
[Clearing condition]
When IRRI1 is cleared by writing 0
