p = 39 and t = 2. Counter/Timer T0 should be set to 02h. With T0 in Con-
tinuous Mode, the value of PRE0 becomes 9Dh (see Figure 108).
Table 24 lists several commonly used bit rates and the values of XTAL, p,
and t required to derive them. This list is presented for convenience and is
not intended to be exhaustive.
