The MPU Interface

Selecting the Interface Type

With the ST7565P chips, data transfers are done through an

8-bit parallel data bus (D7 to D0) or through a serial data

input (SI). By setting the P/S terminal to “H” or “L”, it sets the

access mode to be either parallel or serial mode as shown in

Table 1.

The Parallel Interface

When the parallel interface has been selected (P/S =“H”),

the interface can be connected directly to either 8080 or

6800 Series MPU (as shown in Table 2) by setting the C86

terminal to either “H” or “L”.

Moreover, data bus signals are recognized according to the

combination of A0, /RD (E), /WR (R/W) signals.

The functions are shown as below in Table 3.
