TCMP
Timer Compared Value
TCMP is a 24-bit compared value register. When the internal 24-bit up counter value is
equal to TCMP value, the TIF flag will set to 1.
Time-out period = (Period of Timer clock input) * (8-bit PR 1) * (24-bit TCMP).
Note1:
Never write 0x0 or 0x1 in TCMP field, or the core will run into unknown state.
Note2:
When timer is operating at continuous counting mode, the 24-bit up counter will
keep counting continuously even if user writes a new value into TCMP field. But if timer is
operating at other modes, the 24-bit up counter will restart counting and using newest
TCMP value to be the timer compared value if user writes a new value into TCMP field.
