Timer/counter2 Control Register (T2CON)
TF2
Timer 2 overflow flag.
Cleared by software. TF2 will not be set when either
baud rate generation mode or clock out mode.
Timer 2 External Flag.
Set on a negative transition on T2EX and EXEN2 = 1. In
auto reload mode it is toggled on an under or overflow. Cleared by software.
Receive clock 0 flag.
When set, causes the UART to use Timer 2 overflow
pulses. RCLK0 = 0 causes Timer 1 overflow pulses to be used.
Transmit clock 0 flag.
When set, causes the UART to use Timer 2 overflow
pulses. TCLK0 = 0 causes Timer 1 overflow pulses to be used.
Timer 2 external enable flag.
When set, allows a capture or reload to occur,
together with an interrupt, as a result of a negative transition on input T2EX if in
capture mode or auto reload mode with DCEN reset. If in auto reload mode and
DCEN is set, this bit has no influence. In the other modes, EXF2 is set and an
interrupt is generated on a HIGH-to-LOW transition on T2EX pin. In all modes,
EXEN2 = 0 causes Timer 2 to ignore events at T2EX.
START/STOP control bit.
A logic 1 starts Timer 2.
Counter Timer selection bit.
A logic 1 selects the counter for Timer 2.
Capture/Reload flag.
Selection of mode capture or reload.
