7.5.2 Serial Module Example Configuration Code
The following code is an example of a configuration sequence for the serial module.
***************************************************************************
* MC68340 basic serial module register initialization example code.
* This code is used to initialize the 68340's internal serial module registers,
* providing basic functions for operation.
* It sets up serial channel A for communication with a 9600 baud terminal.
* Note: All serial module registers must be accessed as bytes.
