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 as
serted low, it indicates that a 16-bit data transfer is active on PCMCIA
bus. In ATA extension 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 ATA extension mode, this
signal is used during DMA with the DREQ, IOR# and IOW# signals to
transfer data between the host and the MX9691A. 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 ATA extension mode, this signal accesses the
MX9691A 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 ATA extension mode, this signal accesses the MX9691A
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 MX9691A is configured to respond to I/O card read
cycles at all addresses. In ATA extension mode, this signal is DREQ
and is issued during DMA transfers to indicate that the MX9691A 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 ATA
extension 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 con
figuration registers. In ATA extension mode, this active low signal is
used between two embedded ATA drive to indicate that the drive in
slave mode has passed diagnostics.
