Interrupts due to compare-match and
overflow are disabled
TCNT is cleared by compare-match A
TCNT is incremented on internal clock:
φ/4
0 output on compare-match B
1 output on compare-match A
FRC is incremented on internal clock: φ/8
IVG signal period =
φ × 262144 (1024 times IHG signal)
OCRA is set to the operating mode in
which OCRAR and OCRAF are used
