Unused bit, read as 0
Defines the TMR1 active edge of the timer/event counter:
In Event Counter Mode (T1M1,T1M0)=(0,1):
1:count on falling edge;
0:count on rising edge
In Pulse Width measurement mode (T1M1,T1M0)=(1,1):
1: start counting on the rising edge, stop on the falling edge;
0: start counting on the falling edge, stop on the rising edge
Enables/disables the timer counting (0=disable; 1=enable)
Defines the TMR1 internal clock source.
