6. EXAMPLE MICROCOMPUTER PROCESSING FLOW
This chapter provides an example of the processing flow for controlling the
μ
PD72042A or
μ
PD72042B from the
microcomputer. The main parts of this example processing flow are the following two routines:
Main routine
Performs processing based on the communication flags set by the interrupt routine.
Interrupt routine
Sets the communication flags by reading the statuses of the
μ
PD72042A or
μ
PD72042B upon the issue of an
interrupt request.
