The bits of OC7M correspond bit-for-bit with the bits of timer port
(PORTT). 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.
Read or write anytime.
The bits of OC7D correspond bit-for-bit with the bits of timer port
(PORTT). When a successful OC7 compare occurs, for each bit that
is set in OC7M, the corresponding data bit in OC7D is stored to the
corresponding bit of the timer port.
When the OC7Mn bit is set, a successful OC7 action will override a
successful OC[6:0] compare action during the same cycle; therefore,
the OCn action taken will depend on the corresponding OC7D bit.
A full access for the counter register should take place in one clock
cycle. A separate read/write for high byte and low byte will give a
different result than accessing them as a word.
Read anytime.
