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 values in the 8/16-bit composite timer 00/01 data register and counter. It
incorporates a latch to temporarily store the 8/16-bit composite timer 00/01 data register value.
8/16-bit composite timer 00/01 data register
The 8/16-bit composite timer 00/01 data register is used to write the maximum value counted during
interval timer or PWM timer operation and to read the count value during PWC timer or input capture
operation.
