Divisor Latch
The ACC baud rate is selected by programming the least significant
byte (LSB) and most significant byte (MSB) of the Divisor Latch
shown in Figure 11-6. The Divisor Latch is programmed with an
integer value that divides the ACC oscillator reference frequency of
18.432 MHz into a value of 16 times the baud rate for both trans-
mission and reception of serial data. The most common baud rate
divisors are shown in Table 11-4 on page 11-22.
