• Bit 0—Input Capture/Compare-Match Flag 2A (IMF2A): Status flag that indicates GR2A
input capture or compare-match.
Bit 0: IMF2A
0
1
Description
[Clearing condition]
(Initial value)
When IMF2A is read while set to 1, then 0 is written to IMF2A
[Setting conditions]
• When the TCNT2A value is transferred to GR2A by an input capture
signal while GR2A is functioning as an input capture register
• When TCNT2A = GR2A while GR2A is functioning as an output compare
register
TSR2B: TSR2B indicates the status of channel 2 compare-match and overflow.

Note: * Only 0 can be written to clear the flag.
• Bits 15 to 9—Reserved: These bits are always read as 0. The write value should always be 0.
• Bit 8—Overflow Flag 2B (OVF2B): Status flag that indicates TCNT2B overflow.
Bit 8: OVF2B
0
1
Description
[Clearing condition]
(Initial value)
When OVF2B is read while set to 1, then 0 is written to OVF2B
[Setting condition]
When the TCNT2B value overflows (from H'FFFF to H'0000)
