Description
Interrupts due to compare-match and
overflow are disabled
TCNT is cleared by the rising edge of the
external reset signal (inverse of the IVI
signal)
of the external clock (IHI signal)
Not changed by compare-match B;
output inverted by compare-match A
(toggle output)
When TCORB < TCORA, 1 output on
compare-match B, 0 output on compare-
match A
Compare-match on the 4th (example)
rise of the IHI signal after the rise of the
inverse of the IVI signal
TCNT is incremented on the rising edge
