Timing Systems
FOC[1:5] — Force Output Comparison Bit
Bits [2:0] — Unimplemented
9.4.3 Output Compare Mask Register
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 PA[7:3].
OC1M[7:3] — Output Compare Masks
Bits [2:0] — Unimplemented
9.4.4 Output Compare Data Register
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] — Unimplemented
136
When the FOC bit associated with an output compare circuit is set, the output compare circuit
immediately performs the action it is programmed to do when an output match occurs.
