Interrupt Request Register 2 (IRR2)
Note:
IRR2 is an 8-bit read/write register, in which a corresponding flag is set to 1 when a direct
transfer, A/D converter, or SCI1 interrupt is requested. The flags are not cleared automatically
when an interrupt is accepted. It is necessary to write 0 to clear each flag. Upon reset, IRR2 is
initialized to H'00.

Clearing condition:
When IRRIn = 1, it is cleared by writing 0
Setting condition:
When pin IRQ
is input
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 SYSCR2
