Z86017/Z16017 PCMCIA Interface Solution
Product Specification
8
ZX6017 device. After the host writes new values to the EEPROM
through these registers, the new values are loaded into the ZX6017 at
Power-On Reset (POR).
Note:
The values written register 05h offset the CCR registers and the
three special EEPROM programming registers on the next POR.
