Use OC1M with OC1 to specify the bits of port A that are affected by a successful
OC1 compare. The bits of the OC1M register correspond to PA7–PA3.
OC1M7–OC1M3 — Output Compare Masks
Bits 2–0 — Not implemented; always read 0.
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.
Bits 2–0 — Not implemented; always read 0.
