TIMER 2 CAPTURE LSB
RCAP2L:This register is used to capture the TL2 value when a timer 2 is configured in capture mode.
TIMER 2 CAPTURE MSB
RCAP2H:This register is used to capture the TH2 value when a timer 2 is configured in capture mode.
TIMER 2 LSB
TL2:
Hardware Clear INT5 flag. Setting this bit allows the flag of external interrupt 5 to be
automatically cleared by hardware while entering the interrupt service routine.
Hardware Clear INT4 flag. Setting this bit allows the flag of external interrupt 4 to be
automatically cleared by hardware while entering the interrupt service routine.
Hardware Clear INT3 flag. Setting this bit allows the flag of external interrupt 3 to be
automatically cleared by hardware while entering the interrupt service routine.
Hardware Clear INT2 flag. Setting this bit allows the flag of external interrupt 3 to be
automatically cleared by hardware while entering the interrupt service routine.
automatically reset Timer 2 while the value in TL2 and TH2 have been transferred into the
capture register.
timer 2 counts in 16-bit auto-reload mode.
Timer 2 LSB
RCAP2L is also used as the LSB of a 16-bit reload value when timer 2 is configured in auto-
reload mode.
RCAP2H is also used as the MSB of a 16-bit reload value when timer 2 is configured in
auto-reload mode.
