Timer 1 Generated Baud Rates
When Timer 1 is used as the baud rate generator, the baud rates
in Modes 1 and 3 are determined by the Timer 1 overflow rate and
the value of SMOD as follows:
Modes and Baud Rate =
(
/

The Timer 1 interrupt should be disabled in this application.
The timer itself can be configured for either timer or counter
operation, and in any of its three running modes. In the most
typical application, it is configured for timer operation in the
Autoreload
mode (high nibble of TMOD = 0010 binary). In that
case, the baud
rate is given by the formula:
Modes and Baud Rate=

Table XXV shows some commonly used baud rates and how
they might be calculated from a core clock frequency of 16.78 MHz
and 2.0971 MHz. Generally speaking, a 5% error is tolerable
using asynchronous (start/stop) communications.

Timer 2 Generated Baud Rates
Baud rates can also be generated using Timer 2. Using Timer 2
is similar to using Timer 1 in that the timer must overflow 16 times
before a bit is transmitted/received. Because Timer 2 has a 16-bit
Autoreload mode, a wider range of baud rates is possible using
Timer 2.
Modes and Baud Rate=(1 16
Therefore, when Timer 2 is used to generate baud rates, the timer
increments every two clock cycles and not every core machine
cycle as before. Thus, it increments six times faster than Timer 1,
and therefore baud rates six times faster are possible. Because
Timer 2 has 16-bit autoreload capability, very low baud rates
are still possible.
Timer 2 is selected as the baud rate generator by setting the TCLK
and/or RCLK in T2CON. The baud rates for transmit and receive
can be simultaneously different. Setting RCLK and/or TCLK puts
Timer 2 into its baud rate generator mode as shown in Figure 53.
In this case, the baud rate is given by the formula:
Modes 1 and 3 Baud Rate =
(Core Clk)/(
– RCAP H, RCAP L
