Summary Of Baud Rate Equations
Timer 2 is in baud rate generating mode. If Timer 2 is being clocked
through pin T2(P1.0) the baud rate is:
Baud Rate
+ Timer 2 Overflow Rate
16
If Timer 2 is being clocked internally, the baud rate is:
Baud Rate
+
f
OSC
[n
[65536
* (RCAP2H, RCAP2L)]]
Where:
n = 16 in 6-clock mode, 32 in 12-clock mode.
fOSC= Oscillator Frequency
To obtain the reload value for RCAP2H and RCAP2L, the above
equation can be rewritten as:
RCAP2H, RCAP2L
+ 65536 *

Timer/Counter 2 Set-up
Except for the baud rate generator mode, the values given for
T2CON do not include the setting of the TR2 bit. Therefore, bit TR2
must be set, separately, to turn the timer on. See Table 6 for set-up
of Timer 2 as a timer. Also see Table 7 for set-up of Timer 2 as a
counter.

NOTES:
1. Capture/reload occurs only on timer/counter overflow.
2. Capture/reload occurs on timer/counter overflow and a 1-to-0
transition on T2EX (P1.1) pin except when Timer 2 is used in the
baud rate generator mode.
