Equation 21.2. Timer 1 Overflow Rate
When Timers 2, 3, or 4 are selected as a baud rate source, the baud rate is generated as shown in
Equation 21.3.

=
1 16
Timer234_OverflowRate
Equation 21.3. Mode 1 Baud Rate using Timer 2, 3, or 4
The overflow rate for Timer 2, 3, or 4 is determined by the clock source for the timer (TnCLK) and the 16-
bit reload value stored in the RCAPn register (n = 2, 3, or 4), as shown in Equation 21.4.
