21.6.1 Software Gate Mode
This mode corresponds to legacy Timer2 operation. The timer
increments with each clock input when ON = 1
and
does not increment when ON = 0
. When the TMRx count
equals the PRx period count, the timer resets on the next clock and continues counting from
0. Operation with the ON bit software controlled is illustrated in Figure 21-3. With PRx = 5, the counter advances
until TMRx = 5, and goes to zero with the next clock.

represent Bit-Set File and Bit-Clear File instructions executed by the CPU to set or clear the ON bit of TxCON. CPU execution is asynchronous to the timer clock input.
