26.4.6 Timer Prescalers

Timers provide input clock (peripheral clock or external clock) prescale options of 1:1, 1:8, 1:64 and 1:256, which can be selected by using the TCKPS[1:0] bits (TxCON[5:4]).

The prescaler counter is cleared when any of the following occurs:

  • A write to the TMRx register
  • Disabling the Timer ON bit (TxCON[15] = 0)
  • Any device Reset
