OMn — Output Mode
OLn — Output Level
To enable output action by OMn and OLn bits on 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.
To operate the 16-bit pulse accumulators A and B (PACA and PACB)
independently of input capture or output compare 7 and 0 respectively
the user must set the corresponding bits IOSn = 1, OMn = 0 and OLn
= 0. OC7M7 or OC7M0 in the OC7M register must also be cleared.
