OMn — Output Mode
OLn — Output Level
To enable output action by OMn and OLn bits on the timer port, the
corresponding bit in OC7M should be cleared.
These eight pairs of control bits are encoded to specify the output
action to be taken as a result of a successful OCn compare. When
either OMn or OLn is one, the pin associated with OCn becomes an
output tied to OCn regardless of the state of the associated DDRT bit.

MCCNT register ($B6, $B7) clears the MCZF flag in the
MCFLG register ($A7). This has the advantage of eliminating
software overhead in a separate clear sequence. Extra care is
required to avoid accidental flag clearing due to unintended
accesses.
