Section 10 Advanced Timer Unit (ATU)
Timer Status Registers AH and AL (TSRAH, TSRAL)
TSRAH indicates the status of channel 0 interval interrupts.
Note:
Bits 7 to 4—Reserved: These bits are always read as 0, and should only be written with 0.
Bit 3—Interval Interrupt Flag (IIF3): Status flag that indicates the generation of an interval
interrupt.
Bit 3:
IIF3
0
1
Bit 2—Interval Interrupt Flag (IIF2): Status flag that indicates the generation of an interval
interrupt.
Bit 2:
IIF2

REJ09B0273-0500
Initial value:
* Only 0 can be written, to clear the flag.
Description
[Clearing condition]
When IIF3 is read while set to 1, then 0 is written in IIF3
[Setting condition]
When 1 is generated by AND of ITVE3 in ITVRR and bit 13 of TCNT0L
