Control bit for the external enable mask on a pin. When this bit is clear, do not check
status of the TMR1ENMSK pin. When this bit is set, check status of the TMR1ENMSK pin.
Set this bit to enable counting. To change other register bits, this bit must be cleared.
Set this bit to enable bi-directional alternation mode.
Initial count direction after enabling the timer. Clear this bit to count up; set this bit to
count down.
Clear this bit for auto repetition mode. Set this bit for a single shot.
Clock divider setting (N). The possible clock divisors are: 0 - 2^N (N=0..10).
Set this bit to enable clock source glitch filtering.
Clock source edge selection. Clear this bit for rising edge; set this bit for falling edge.
Clock source selection: 0 = calibrated RC oscillator (default); 1 = 32kHz; 2 = 12MHz; 3 =
External (GPIO).
