Using Timer 1 to Generate 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 1,3 baud rate = 2
SMOD
/32

(timer 1 overflow 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 3 running modes. In the most typical
applications, it is configured for “timer” operation, in the auto-reload mode (high nibble of
TMOD=0010B). In that case, the baud rate is given by the formula
Modes 1,3 baud rate = 2
SMOD

(256–TH1)]
One can achieve very low baud rates with timer 1 by leaving the timer 1 interrupt enabled, and
configuring the timer to run as a 16-bit timer (high nibble of TMOD = 0001B), and using the timer 1
interrupt to do a 16-bit software reload.
Table 6-7
lists commonly used baud rates and how they can be obtained from timer 1.
