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 = CDH, CCH respectively.
RCAP2H and RCAP2L
Timer 2, Capture/Reload byte and low byte.
SFR Address = CBH, CAH respectively.

Description
Timer 2 Overflow Flag.
Set by hardware on a Timer 2 overflow. TF2 will not be set when either RCLK = 1 or TCLK = 1.
Cleared by user software.
Timer 2 External Flag.
Set by hardware when either a capture or reload is caused by a negative transition on T2EX and EXEN2 = 1.
Cleared by user software.
Receive Clock Enable Bit.
Set by user to enable the serial port to use Timer 2 overflow pulses for its receive clock in serial port
Modes 1 and 3.
Cleared by user to enable Timer 1 overflow to be used for the receive clock.
Transmit Clock Enable Bit.
Set by user to enable the serial port to use Timer 2 overflow pulses for its transmit clock in serial port
Modes 1 and 3.
Cleared by user to enable Timer 1 overflow to be used for the transmit clock.
Timer 2 External Enable Flag.
Set by user to enable a capture or reload to occur as a result of a negative transition on T2EX if
Timer 2 is not being used to clock the serial port.
Cleared by user for Timer 2 to ignore events at T2EX.
Timer 2 Start/Stop Control Bit.
Set by user to start Timer 2.
Cleared by user to stop Timer 2.
Timer 2 Timer or Counter Function Select Bit.
Set by user to select counter function (input from external T2 pin).
Cleared by user to select timer function (input from on-chip core clock).
Timer 2 Capture/Reload Select Bit.
Set by user to enable captures on negative transitions at T2EX if EXEN2 = 1.
Cleared by user to enable auto-reloads with Timer 2 overflows or negative transitions at T2EX
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.
