Interfacing the HD66702
Interface to MPUs
Interfacing to an 8-bit MPU
See Figure 16 for an example of using a I/O port (for a single-chip microcomputer) as an interface
device.
In this example, A0 to A7 are connected to the data bus DB0 to DB7, and C0 to C2 are connected to E,
R/
W
, and RS, respectively.
