Function
ET2
Timer 2 overflow / external reload interrupt enable.
If ET2 = 0, the timer 2 interrupt is disabled.
If ET2 = 1, the timer 2 interrupt is enabled.
EXEN2
Timer 2 external reload interrupt enable
If EXEN2 = 0, the timer 2 external reload interrupt is disabled.
If EXEN2 = 1, the timer 2 external reload interrupt is enabled. The external reload
function is not affected by EXEN2.
EXF2
Timer 2 external reload flag
EXF2 is set when a reload is caused by a falling edge on pin T2EX while EXEN2 =
1. If ET2 in IEN0 is set (timer 2 interrupt enabled), EXF2 = 1 will cause an interrupt.
EXF2 can be used as an additional external interrupt when the reload function is
not used. EXF2 must be cleared by software.
TF2
Timer 2 overflow flag
Set by a timer 2 overflow and must be cleared by software. If the timer 2 interrupt
is enabled, TF2 = 1 will cause an interrupt.
