Timer 3 in Gated Timer Mode
Gated timer mode for the core timer T3 is selected by setting bit field T3M in register
T3CON to ‘010
Bit T3M.0 (T3CON.3) selects the active level of the gate input. In gated timer mode the
same options for the input frequency as for the timer mode are available. However, the
input clock to the timer in this mode is gated by the external input line T3IN (Timer T3
External Input), which is an alternate function of P3.6.
To enable this operation pin P3.6/T3IN must be configured as input, ie. direction control
bit DP3.6 must contain ’0’.
