HC5:
HC4:
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.
HC3: 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.
HC3: 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.
T2CR: Timer 2 Capture Reset. In the Timer 2 Capture Mode this bit enables/disables hardware
automatically reset Timer 2 while the value in TL2 and TH2 have been transferred into the
capture register.
T2OE: Timer 2 Output Enable. This bit enables/disables the Timer 2 clock out function.
DCEN: Down Count Enable: This bit, in conjunction with the T2EX pin, controls the direction that
timer 2 counts in 16-bit auto-reload mode.

RCAP2L.6 RCAP2L.5 RCAP2L.4 RCAP2L.3 RCAP2L.2 RCAP2L.1 RCAP2L.0
Mnemonic: RCAP2L
Address: CAh
RCAP2L:This register is used to capture the TL2 value when a timer 2 is configured in capture mode.
RCAP2L is also used as the LSB of a 16-bit reload value when timer 2 is configured in auto-
reload mode.

RCAP2H.7 RCAP2H.6 RCAP2H.5 RCAP2H.4 RCAP2H.3 RCAP2H.2 RCAP2H.1 RCAP2H.0
Mnemonic: RCAP2H
Address: CBh
RCAP2H: This register is used to capture the TH2 value when a timer 2 is configured in capture mode.
RCAP2H is also used as the MSB of a 16-bit reload value when timer 2 is configured in
auto-reload mode.
