NOTES:

1. When the ZX6017 is in Master Mode, the user should program this location in EEPROM with 00h.

The PCMCIA base address for these registers could be set in the range of 000h–400h. At Power-On Reset

(POR), the base is set to 000h.

3. User must write the Revision Number (see ZX6017 top mark) to the Revision Control register to unlock these registers.

4. The Z86017 BA Revision Number is 10h (see device top mark).

5. These registers are only available on the Z16017.

6. When the ZX6017 is in Master Mode, data at EEPROM addresses 30h–FFh are written locations 00h–CFh of the on-board Attribute Memory.

In Slave Mode, Attribute Memory is programmed through registers 08h and 09h.
