(2) Examples of settings when external baud rate input (ASCK) is used
432
Table 16-5 shows an example of setting when external baud rate input (ASCK) is used. When using the ASCK input,
clear the SCK bit of the asynchronous serial interface mode register (ASIM) to 0, and set the corresponding pin in the
control mode by using PMC3 or PMC1.
