5. 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 FC, or Timer C interrupt is requested. The
flags are not cleared automatically when an interrupt is accepted. It is necessary to write 0 to clear
each flag.

is an internal signal that performs interfacing to the FLEX™ decoder incorporated in
Description
Clearing conditions:
When IRRIn = 1, it is cleared by writing 0
Setting conditions:
When pin IRQn is designated for interrupt input and the designated
signal edge is input
Description
Clearing conditions:
When IRRDT = 1, it is cleared by writing 0
Setting conditions:
When a direct transfer is made by executing a SLEEP instruction
