Auto-reload is the default mode. Capture mode causes data in TL2 and TH2
to be transferred to the capture registers RCAP2L and RCAP2H when there is
a 1-to-0 transition on T2EX (port 1.1).
Timer 1 can be used as the serial port baud rate generator but has limitations
on the minimum baud rate. For example, with an oscillator frequency of
Figure 4.11 Simulation display with breakpoint used to determine timing
Timer 2 79
11.0592MHz the baud rate generation can only go down to the standard rate
of 4800, for lower values the oscillator frequency must be lowered. Timer 2
having 16-bit auto-reload gets over this problem. (See Section 4.9.)
The control register associated with timer 2 is T2CON.
