Interrupt Request Register 2 (IRR2)
IRR2 is an 8-bit read/write register, in which a corresponding flag is set to 1 when a direct
transfer, A/D converter, Timer G, Timer FH, Timer FL, Timer C, or asynchronous event counter
interrupt is requested. The flags are not cleared automatically when an interrupt is accepted. It is
necessary to write 0 to clear each flag.

Note: * Only a write of 0 for flag clearing is possible
Description
Clearing condition:
When IRRIn = 1, it is cleared by writing 0
Setting condition:
When pin IRQn is designated for interrupt input and the designated signal edge is
input
Description
Clearing condition:
When IRRDT = 1, it is cleared by writing 0
Setting condition:
When a direct transfer is made by executing a SLEEP instruction while DTON = 1 in
