Addressing Modes

• The ZX6017 supports all PCMCIA Addressing Modes:

• PCMCIA Common Memory Mode

• PCMCIA I/O Mode

• PCMCIA ATA_IDE Mode

• Pass-through ATA/IDE-to-ATA/IDE Mode

Note: This mode is for users who have a 68-pin PCMCIA connector,

but are using ATA/IDE protocol instead of PCMCIA protocol.

The overall ZX6017 mode of operation is controlled by the Interface

Configuration Register (00h) bits 3,2. 00 in these two bits sets the device

to ATA/IDE mode if the PC_ATA/HOE pin is Low on power-up and into

PCMCIA mode if the pin is High. The default for this register is 00 and

the PC_ATA/HOE pin determines the mode of operation, PCMCIA or

ATA/IDE. Table 4 describes these addressing modes.

one card.

To place the ZX6017 into proper Addressing mode, a set of Configuration

Registers and Memory Maps reside on-chip.
