GATE1: Timer 1 Gate Control.
0: Timer 1 enabled when TR1 = 1 irrespective of INT1 logic level.
1: Timer 1 enabled only when TR1 = 1 AND INT1 is active as defined by bit IN1PL in register
INT01CF (see SFR Definition 9.13).
C/T1: Counter/Timer 1 Select.
0: Timer Function: Timer 1 incremented by clock defined by T1M bit (CKCON.3).
1: Counter Function: Timer 1 incremented by high-to-low transitions on external input pin
(T1).
These bits select the Timer 1 operation mode.
GATE0: Timer 0 Gate Control.
0: Timer 0 enabled when TR0 = 1 irrespective of INT0 logic level.
1: Timer 0 enabled only when TR0 = 1 AND INT0 is active as defined by bit IN0PL in register
INT01CF (see SFR Definition 9.13).
C/T0: Counter/Timer Select.
0: Timer Function: Timer 0 incremented by clock defined by T0M bit (CKCON.2).
1: Counter Function: Timer 0 incremented by high-to-low transitions on external input pin
(T0).
These bits select the Timer 0 operation mode.
