OC7M[7:0] Bits
OC7M has priority over output action on the timer port enabled by OMn and OLn
bits in TCTL1 and TCTL2. If an OC7M bit is set, it prevents the action of
corresponding OM and OL bits on the selected timer port.
The bits of OC7M correspond bit-for-bit with the timer port (PORTT) bits. Setting
the OC7Mn will set the corresponding port to be an output port regardless of the
state of the DDRTn bit, when the corresponding TIOSn bit is set to be an output
compare. This does not change the state of the DDRT bits. At successful OC7,
for each bit that is set in OC7M, the corresponding data bit OC7D is stored to
the corresponding bit of the timer port. See
