For counter operation, a port pin associated to line T3IN must be configured as input.
The maximum input frequency which is allowed in counter mode is
f
hw_clk
/8 (BPS1 = ‘01’).
To ensure that a transition of the count input signal which is applied to T3IN is correctly
recognized, its level should be held high or low for at least 4
f
hw_clk
cycles (BPS1 = ‘01’)
before it changes.
Timer 3 in Incremental Interface Mode
Incremental Interface mode for the core timer T3 is selected by setting bit field T3M in
register T3CON to ‘110
B
’ or ‘111
B
’. In Incremental Interface mode the two inputs
associated with timer T3 (T3IN, T3EUD) are used to interface to an incremental encoder.
T3 is clocked by each transition on one or both of the external input lines which gives 2-
fold or 4-fold the resolution of the encoder input.

Block Diagram of Core Timer T3 in Incremental Interface Mode
The T3I bit field in control register T3CON selects the triggering transitions (see
Table 7-
4
). In this mode, the sequence of the transitions of the two input signals is evaluated and
generates count pulses as well as the direction signal. Depending on the chosen
Incremental Interface Mode, rotation detection ‘110

’, an
interrupt is generated. For the rotation detection, an interrupt will be generated each time
the count direction of timer T3 changes. For the edge detection an interrupt will be
