Timer/counter2 Control Register (T2CON)
TF2
Timer 2 overow ag. Cleared by software. TF2 will not be set when either
baud rate generation mode or clock out mode.
EXF2
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 overow. Cleared by software.
RCLK0
Receive clock 0 ag. When set, causes the UART to use Timer 2 overow
pulses. RCLK0 = 0 causes Timer 1 overow pulses to be used.
TCLK0
Transmit clock 0 ag. When set, causes the UART to use Timer 2 overow
pulses. TCLK0 = 0 causes Timer 1 overow pulses to be used.
EXEN2
Timer 2 external enable ag. 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 inuence. 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.
TR2
START/STOP control bit. A logic 1 starts Timer 2.
C/T2
Counter Timer selection bit. A logic 1 selects the counter for Timer 2.
CP/RL2
Capture/Reload ag. Selection of mode capture or reload.
