Table 9-7. Data Formats in Asynchronous Mode
Note
(2) Clock: In asynchronous mode it is possible to select either an internal clock created by the on-
chip baud rate generator, or an external clock input at the SCK pin. Refer to table 9-6.
If an external clock is input at the SCK pin, its frequency should be 16 times the desired baud rate.
If the internal clock provided by the on-chip baud rate generator is selected and the SCK pin is used
for clock output, the output clock frequency is equal to the baud rate, and the clock pulse rises at
the center of the transmit data bits. Figure 9-3 shows the phase relationship between the output
clock and transmit data.
