A typical control mode application is illustrated in Figure 16. In this
example, an industrial process is to be monitored. The occurrence of any
abnormal operating condition is to be reported to a Z80 CPU-based control
system. The process control and status word has the following format:
The PIO may be used as follows. First, Port A is set for Mode 3 operation
by writing the following control word to Port A.
Whenever Mode 3 is selected, the next control word sent to the port must
be an I/O select word. In this example, port data lines A5, A3, and A0 are
selected as inputs, and the following control word is written:
Next, the appropriate interrupt vector must be loaded (refer to the Z80 CPU
User’s Manual for details):
An interrupt control word is next sent to the port:
The mask word following the interrupt mode word is:
