The MPU Interface
Selecting the Interface Type
With the ST7565S chips, data transfers are done through an
8-bit parallel data bus (D7 to D0) or through a serial data
input (SI). Through selecting the P/ S terminal polarity to the
The Parallel Interface
When the parallel interface has been selected (P/S =“H”),
then it is possible to connect directly to either an
Moreover, data bus signals are recognized by a combination
of A0, /RD (E), /WR (R/W) signals, as shown in Table 3.
