Function
Timer 2 value low byte
The TL2 register holds the 8-bit low part of the 16-bit timer 2 count value.
Timer 2 value high byte
The TH2 register holds the 8-bit high part of the 16-bit timer 2 count value.
Compare / reload / capture register low byte
CRCL is the 8-bit low byte of the 16-bit reload register of timer 2. It is also used for
compare/capture functions.
Compare / reload / capture register high byte
CRCH is the 8-bit high byte of the 16-bit reload register of timer 2. It is also used for
compare/capture functions.
