12.2 Timer Registers
CFORC — Timer Force Compare
FOCx — Force Output Compare x Action
Bits [2:0] — Not implemented. Reads always return zero and writes have no effect.
OC1M — Output Compare 1 Mask
OC1M[7:3] — Output Compare Masks
Bits [2:0] — Not implemented. Reads always return zero and writes have no effect.
OC1D — Output Compare 1 Data
OC1D[7:3] — Output Compare Data
Bits [2:0] — Not implemented. Reads always return zero and writes have no effect.
TCNT — Timer Count

Bits set in OC1M allow OC1 to output the corresponding OC1D bits in port A when a successful com-
pare event occurs.
Data in OC1Dx is output to port A bit x on successful OC1 compares if OC1Mx is set.
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
to be latched into a buffer for the next CPU cycle so that a double-byte read returns the full 16-bit state
of the counter at the time of the MSB read cycle.
0 = Not affected
1 = Output compare x action occurs, but OCxF flag bit is not set
0 = Control of the corresponding port A pin is disabled
1 = Control of the corresponding port A pin is enabled
