T2CON - SFR C8h (Table C-6.)
RCAP2L - SFR CAh - Used to capture the TL2 value when Timer 2 is configured for
capture mode, or as the LSB of the 16-bit reload value when Timer 2 is configured for
auto-reload mode.
RCAP2H - SFR CBh - Used to capture the TH2 value when Timer 2 is configured for
capture mode, or as the MSB of the 16-bit reload value when Timer 2 is configured for
auto-reload mode.
TL2 - SFR CCh - Lower 8 bits of the 16-bit count.
TH2 - SFR CDh - Upper 8 bits of the 16-bit count.
