Register Description:
TF2
T2CON.7 Timer 2 overflow flag set by hardware
and cleared by software. TF2 cannot
be set when either RCLK = 1 or TCLK
= 1.
EXF2 T2CON.6 Timer 2 external flag set when either a
capture or reload is caused by a
negative transition on T2EX, and
EXEN2 = 1. When Timer 2 interrupt is
enabled, EXF2 = 1 causes the CPU to
vector to the Timer 2 interrupt routine.
EXF2 must be cleared by software.
RCLK T2CON.5 Receive clock flag. When set, causes
the Serial Port to use Timer 2 overflow
pulses for its receive clock in modes 1
and 3. RCLK = 0 causes Timer 1
overflow to be used for the receive
clock.
TLCK T2CON.4 Transmit clock flag. When set, causes
the Serial Port 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.
EXEN2 T2CON.3
Timer 2 external enable flag. When
set, allows a capture or reload to occur
as a result of 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.
TR2
T2CON.2 Software START/STOP control for
Timer 2. A logic 1 starts the Timer.
C/T2 T2CON.1 Timer or Counter select. 0 = Internal
Timer. 1 = External Event Counter
(triggered by falling edge).
CP/RL2 T2CON.0
Capture/Reload flag. When set,
captures occur on negative transitions
at T2EX if EXEN2 = 1. When cleared,
auto-reloads 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.
