Timer 2 Overflow Toggle Mask bit
T2OTM = 0, disable overflow toggle
T2OTM = 1, enable overflow toggle, a counter overflow (OVF2) toggles output
Timer 2 Compare Toggle Mask bit
T2CTM = 0, disable compare toggle
T2CTM = 1, enable compare toggle, a match of the counter with the compare
Timer 2 Reset Mask bit
T2RM = 0, disable counter reset
T2RM = 1, enable counter reset, a match of the counter with the compare register
Timer 2 Interrupt Mask bit
T2IM = 0, disable Timer 2 interrupt
T2IM = 1, enable Timer 2 interrupt

T2CTM
resets the counter
flip-flop (TOG2). If the T2OTM bit is set, only a counter overflow
can generate an interrupt except on the Timer 2 output mode 7
register toggles output flip-flop (TOG2). In Timer 2 output mode 7
and when the T2CTM bit is set, only a match of the counter with the
compare register can generate an interrupt
