NOTE:
REG[3:0] — 64-Byte Register Block Map Position
Can be written only once in first 64 cycles out of reset in normal modes or at
any time in special modes.
If OC1Mx is set, data in OC1Dx is output to port A bit x on successful OC1
compares.
Bits [2:0]— Unimplemented
OC1M[7:3] — Output Compare Masks
