In UART modes 1 and 3 of UART module, Timer 1 can be used for generating the
variable baud rates. In theory, this timer could be used in any of its modes. But in
practice, it should be set into auto-reload mode (Timer 1 mode 2), with its high byte set
to the appropriate value for the required baud rate. The baud rate is determined by the
Timer 1 overflow rate and the value of SMOD as follows:
3.14
Setting bit FDM in register FDCON to 1 configures the fractional divider to normal divider
mode, while at the same time disables baud rate generation (see
fractional divider is enabled (FDEN = 1), it functions as an 8-bit auto-reload timer (with
no relation to baud rate generation) and counts up from the reload value with each input
clock pulse. Bit field RESULT in register FDRES represents the timer value, while bit
field STEP in register FDSTEP defines the reload value. At each timer overflow, an
overflow flag (FDCON.NDOV) will be set and an interrupt request generated. This gives
an output clock f
The output frequency in normal divider mode is derived as follows:
