6.5.1 Capture mode
Table 21.
Table 22.
Not bit addressable; Reset value: XX00 0000B
Table 23.
In the Capture mode there are two options which are selected by bit EXEN2 in T2CON. If
EXEN2 = 0 Timer 2 is a 16-bit timer or counter (as selected by C/T2 in T2CON) which
upon overflowing sets bit TF2, the Timer 2 overflow bit.
The capture mode is illustrated in

Description
Transmit clock flag. When set, causes the UART to use Timer 2
overflow pulses for its transmit clock in modes 1 and 3. TCLK = 0
causes Timer 1 overflows to be used for the transmit clock.
Timer 2 external enable flag. When set, allows 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. EXEN2 = 0 causes Timer 2 to
ignore events at T2EX.
Start/stop control for Timer 2. A logic ‘1’ enables the timer to run.
Timer or counter select. (Timer 2)
Capture/Reload flag. When set, captures will occur on negative
transitions at T2EX if EXEN2 = 1. When cleared, auto-reloads will
occur either 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 auto-reload on Timer 2 overflow.
Description
Reserved for future use. Should be set to ‘0’ by user programs.
Timer 2 Output Enable bit. Used in programmable clock-out mode
only.
Down Count Enable bit. When set, this allows Timer 2 to be configured
as an up/down counter.
0 = internal timer (f
1 = external event counter (falling edge triggered; external clock’s
maximum rate = f
