An overflow or underflow of timer T3 can also be used to clock other timers. For this
purpose, there is the special output line T3OFL.
Timer 3 in Timer Mode
Timer mode for the core timer T3 is selected by setting bit field T3M in register T3CON
to ‘000
In this mode, T3 is clocked with the module clock f
prescaler, which is controlled by bit field T3I and bit FM1. The input frequency f
T3 and its resolution r
be seen from the following formula:

This formula also applies to the Gated Timer Mode of T3 and to the auxiliary timers T2
and T4 in timer and gated timer mode.
