Timer 3 Edge Interrupt Mask
T3EIM = 0, disables the interrupt when an edge event for Timer 3 occurs (T3I)
T3EIM = 1, enables the interrupt when an edge event for Timer 3 occurs (T3I)
Timer 3 Toggle Output Preset T3TOP = 0, sets toggle output (M3) to '0'
Timer 3 Toggle with Start . T3TS = 0, Timer 3 output is not toggled during the start
Timer 3 Run
Timer 3 Edge Detect
This bit will be set by the edge-detect logic of Timer 3 input (T3I)
Timer 3 Compare 2
This bit will be set when a match occurs between Counter 3 and T3CO2
Timer 3 Compare 1
This bit will be set when a match occurs between Counter 3 and T3CO1
