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
