● 8-bit counter
This counter serves as the basis for various timer operations. It can be used either as two 8-bit
counters or as a 16-bit counter.
● 8-bit comparator
The comparator compares the value in the 8/16-bit composite timer data register and that in the
counter. It incorporates a latch that temporarily stores the 8/16-bit composite timer data register
value.
