Table 148 lists the synchronous interface specifications and the means of 
configuring the interface parameters.

Asynchronous transmission uses an internal clock to generate the appropriate 
baud rate for serial controllers.

Table 149 lists asynchronous interface specifications and the means of 
configuring interface parameters.
