For counter operation, a port pin P3.6/T3IN must be configured as input. The maximum
input frequency which is allowed in counter mode is f
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
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 C161U, the T3EUD timer input is connected to P3.5. In this case, Timer 4
