Example Circuit Application
Figure 1.179 shows a circuit application for the standard serial I/O mode 2.
When "00
generator is set to match the operating frequency (2 - 16 MHz). The highest speed is taken from the first 8 transmissions
and the lowest from the last 8. These values are then used to calculate the bit rate generator value for a baud rate of
9,600 bps. Baud rate cannot be attained with some operating frequencies. Table 1.74 lists the operation frequency and
the baud rate.
