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 the timer counting
(0=disable; 1=enable)
Unused bit, read as 0
Define the operating mode (T0M1, T0M0)
01 = Event count mode (External clock)
10 = Timer mode (Internal clock)
11 = Pulse Width measurement mode (External clock)
00 = Unused
