OZ6912
Pin Name
IORD#/
CAD13
Description
I/O Read: This output goes active (low) for I/O
reads from the OZ6912 to the socket.
IOW#/
CAD15
CardBus Address/Data: In CardBus mode, this
pin is the CAD bit 13.
I/O Write: This output goes active (low) for I/O
writes from the OZ6912 to the socket.
WP/
IOIS16#/
CCLKRUN#
CardBus Address/Data: In CardBus mode, this
pin is the CAD bit 15.
Write Protect / I/O is 16-Bit: In Memory mode,
this input is indicates the status of the write
protect switch on the PC Card. In I/O mode, this
input indicates the size of current data transfer on
the PC Card.
INPACK#/
CREQ#
CardBus Clock Run: In CardBus mode, this pin
is the CCLKRUN# signal, which starts and stops
the CardBus CCLK. To enable the CLKRUN#
signal, ExCA register 3Bh bit[3:2] must be
enabled.
Input Acknowledge: The INPACK# function is
not applicable in PCI bus environments. This pin
is provided for Legacy card compatibility.
RDY/IREQ#/
CINT#
CardBus Request: In CardBus mode, this pin is
the CREQ# signal.
Ready / Interrupt Request: In Memory mode,
this input indicates that the card is ready or busy.
In I/O mode, this input indicates a card interrupt
request.
WAIT#/
CSERR#
CardBus Interrupt: In CardBus mode, this pin is
the CINT# signal. This signal is active-low and
level-sensitive.
Wait: This pin is driven by the PC Card to delay
completion of the current cycle.
CD[2:1]/
CCD[2:1]#
CardBus System Error: In CardBus mode, this
pin is the CSERR# signal.
Card Detect: These inputs indicate a card is
present in the socket. They are internally pulled
high to AUX_VCC.
CE2#/
CAD10
CardBus Card Detect: In CardBus mode, these
inputs are used with CVS[2:1] to detect presence
and type of card.
Card Enable 2: This pin is driven low to control
byte/word card access. CE2# enables odd-
numbered address bytes.
CE1#/
CCBE0#
CardBus Address/Data: In CardBus mode, this
pin is the CAD bit 10.
Card Enable 1: This pin is driven low to control
byte/word card access. CE1# enables even-
numbered address bytes. When configured for 8-
bit cards, CE1# is active and A0 is used to
indicate access of odd- or even-numbered bytes.
CardBus Command/Byte Enable: In CardBus
mode, this pin is the CCBEO# signal.
