Defines the TMR0 active edge of the timer/event counter:
In Event Counter Mode (T0M1,T0M0)=(0,1):
1:count on falling edge;
0:count on rising edge
In Pulse Width measurement mode (T0M1,T0M0)=(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
Enable/disable timer counting (0=disabled; 1=enabled)
