TIMER/COUNTER 2 OPERATING MODES
The following paragraphs describe the operating modes for
Timer/Counter 2. The operating modes are selected by bits in
the T2CON SFR as shown in Table XXIX.

16-Bit Autoreload Mode
In Autoreload Mode, there are two options, selected by bit
EXEN2 in T2CON. If EXEN2 = 0, when Timer 2 rolls over it
not only sets TF2 but also causes the Timer 2 registers to be
reloaded with the 16-bit value in registers RCAP2L and RCAP2H,
which are preset by software. If EXEN2 = 1, Timer 2 still performs
the above, but with the added feature that a 1-to-0 transition at
external input T2EX will also trigger the 16-bit reload and set
EXF2. The Autoreload Mode is illustrated in Figure 52.
16-Bit Capture Mode
In the Capture Mode, there are again two options, selected by bit
EXEN2 in T2CON. If EXEN2 = 0, Timer 2 is a 16-bit timer or
counter that, upon overflowing, sets bit TF2, the Timer 2 over-
flow bit, which can be used to generate an interrupt. If EXEN2 = 1,
Timer 2 still performs the above, but a l-to-0 transition on
external input T2EX causes the current value in the Timer 2
registers, TL2 and TH2, to be captured into registers RCAP2L
and RCAP2H, respectively. In addition, the transition at T2EX
causes bit EXF2 in T2CON to be set; EXF2, like TF2, can gener-
ate an interrupt. The Capture Mode is illustrated in Figure 53.
The baud rate generator mode is selected by RCLK = 1 and/or
TCLK = 1.
In either case, if Timer 2 is being used to generate the baud rate,
the TF2 interrupt flag will not occur. Therefore Timer 2 interrupts
will not occur so they do not have to be disabled. However, in
this mode, the EXF2 flag can still cause interrupts and this can
be used as a third external interrupt.
Baud rate generation will be described as part of the UART
serial port operation.
