• 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]

Bit 7: CMF2H
0
1
Description
[Clearing condition]
(Initial value)
When CMF2H is read while set to 1, then 0 is written to CMF2H
