The RCLK1 and TCLK1 Bits in the SFR named PCON control UART1, and have the exact
same function as RCLK and TCLK.

Timer 2 flag, causes interrupt if enabled.
TF2 is set by hardware upon overflow. Must be cleared by
firmware. TF2 will not be set when either RCLK or TCLK =1.
Timer 2 flag, causes interrupt if enabled.
EXF2 is set when a capture or reload is caused by a negative
transition on T2X pin and EXEN2 = 1. EXF2 must be cleared
by firmware.
UART0 Receive Clock control.
When RCLK = 1, UART0 uses Timer 2 overflow pulses for its
receive clock in Modes 1 and 3. RCLK=0, Timer 1 overflow is
used for its receive clock
UART0 Transmit Clock control.
When TCLK = 1, UART0 uses Timer 2 overflow pulses for its
transmit clock in Modes 1 and 3. TCLK=0, Timer 1 overflow is
used for transmit clock
Timer 2 External Enable.
When EXEN2 = 1, capture or reload results when negative
edge on pin T2X occurs. EXEN2 = 0 causes Timer 2 to ignore
events at pin T2X.
Timer 2 run control.
1 = Timer/Counter 2 is on, 0 = Timer Counter 2 is off.
Counter or Timer function select.
When C/T2 = 0, function is timer, clocked by internal clock.
When C/T2 = 1, function is counter, clocked by signal sampled
on external pin, T2.
Capture/Reload.
When CP/RL2 = 1, capture occurs on negative transition at pin
T2X if EXEN2 = 1. When CP/RL2 = 0, auto-reload occurs
when Timer 2 overflows, or on negative transition at pin T2X
when EXEN2=1. When RCLK = 1 or TCLK = 1, CP/RL2 is
ignored, and Timer 2 is forced to auto-reload upon Timer 2
