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.
The bits of this register specify the action taken as a result of a successful OCx
compare.
OM[2:5] — Output Mode Bits
OL[2:5] — Output Level Bits
Register name: Timer Counter Register (High)
Register name: Timer Counter Register (Low)
These control bit pairs are encoded to specify the action taken after a successful
OCx compare. OC5 functions only if the I4/O5 bit in the PACTL register is clear.
