EEPROM Programming Through the PCMCIA

Interface

The ZX6017 can program the serial EEPROM through the PCMCIA

interface. EEPROM programming is accomplished by means of three

special registers that are accessed identically to the CCR registers as

defined by the PCMCIA specification (Figure 4). These registers are

fixed at addresses 7F0, 7F2, and 7F4. The host software reads and writes

each byte of the EEPROM through these registers and configures the
