Set bit(s) to enable OC1 to control corresponding pin(s) of port A.
Use this register with OC1 to specify the data that is to be stored on the affected pin
of port A after a successful OC1 compare. When a successful OC1 compare occurs,
a data bit in OC1D is stored in the corresponding bit of port A for each bit that is set in
OC1M.
If OC1Mx is set, data in OC1Dx is output to port A bit x on successful OC1 compares.
The 16-bit read-only TCNT register contains the prescaled value of the 16-bit timer. A
full counter read addresses the most significant byte (MSB) first. A read of this address
causes the least significant byte (LSB) to be latched into a buffer for the next CPU cy-
cle so that a double-byte read returns the full 16-bit state of the counter at the time of
the MSB read cycle.
In normal modes, TCNT is read-only.
The bits of this register specify the action taken as a result of a successful OCx com-
pare.
0 = OC1 is disabled
1 = OC1 is enabled to control the corresponding pin of port A
