Timer/Counter 2 Data Registers
Timer/Counter 2 also has two pairs of 8-bit data registers associated with it. These are used as both timer data registers and timer
capture/reload registers.
TH2 and TL2
Timer 2, data high byte and low byte.
SFR Address = CDhex, CChex respectively.
RCAP2H and RCAP2L
Timer 2, Capture/Reload byte and low byte.
SFR Address = CBhex, CAhex respectively.

Timer 2 External Enable Flag.
Timer 2 is not being used to clock the serial port.
Timer 2 Start/Stop Control Bit.
Timer 2 Timer or Counter Function Select Bit.
Timer 2 Capture/Reload Select Bit.
when EXEN2 = 1. When either RCLK = 1 or TCLK = 1, this bit is ignored and the timer is
forced to autoreload on Timer 2 overflow.
