Serial EEPROM
The 93C56B is enabled through the Chip Select pin (CS) and accessed via a 3-wire serial
interface consisting of Data Input (DI), Data Output (DO), and Shift Clock (SK). Upon
receiving a Read instruction at DI, the address is decoded, and the data is clocked out seri-
ally on the DO pin. Figure 20 shows the Serial EEPROM schematics.
