Description

WRITE PROTECT or 16-bit I/O TRANSFER :

In PCMCIA mode, this bit has two functions. In PCMCIA

common-memory mode,this signal indicates write protect.

In PCMCIA I/O mode, when IOIS16# is asserted low, it

indicates that a 16-bit data transfer is active on PCMCIA

bus.

In True IDE mode, the IOCS16# signal indicates that a

16-bit buffer transfer is active on the host bus.

This open drain signal is only driven on assertion(low).

Attribute memory and I/O select :

In PCMCIA mode, this signal is used to select attribute

memory and I/O space. In True IDE mode, this signal is

used during DMA with the DREQ, IOR# and IOW# signals

to transfer data between the host and the MX9691L. This pin

includes an internal pull-up resistor.

Card enable 1 or Chip select 0:In PCMCIA mode,this signal

is card enable 1. This signal can enable either even or odd

numbered-address bytes onto HD7:0. In True IDE mode, this

signal accesses the MX9691 command block registers. This

input is ignored during DMA data transfer, i.e. when the

DACK# signal is low. This pin includes an internal pull-up

resistor.

Card enable 2 or Chip select 1:

In PCMCIA mode,this signal is card enable 2. This signal

can enable odd numbered-address bytes onto HD15:8. In

True IDE mode, this signal accesses the MX9691L control

block registers. This pin includes an internal pull-up

resistor.

Input Acknowledge or DMA request :In PCMCIA mode, this

signal is asserted when the MX9691 is configured to respond

to I/O card read cycles at all addresses. In True IDE mode,

this signal is DREQ and is issued during DMA transfers to

indicate that the MX9691L is ready for DMA transfer.

Speaker or slave present : In PCMCIA mode, the

output-enable for this signal is controlled by the card

configuration registers. In True IDE mode, this signal is used

as the slave-present detector.

Status change or pass diagnostics :In PCMCIA mode, this

signal is used to indicate changes in the RDY/BSY#,WP

signals in card configuration registers. In True IDE mode,

this active low signal is used between two embedded ATA

drive to indicate that the drive in slave mode has passed

diagnostics.
