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
(configured as timer input T3IN) and pin P3.5/T3EUD (configured as timer input) are
used to interface to an incremental encoder.
Note: In the INCA-D, the T3EUD timer input is connected to P3.5. In this case, Timer 4
input T4IN can be used only by Software.
