Baud Rate Selection (Modes 1 and 3)
In modes 1 and 3, the Baud Rate is derived either from the Timer 1 or the Internal Baud Rate
Generator and allows different baud rate in reception and transmission.
As shown in Figure 17-12 the selection is done using RBCK and TBCK bits in BDRCON register.
Figure 17-13 gives the baud rate calculation formulas for each baud rate source while Table 114
details Internal Baud Rate Generator configuration for different peripheral clock frequencies and
giving baud rates closer to the standard baud rates.
