cards
Card I/O write
This signal is valid for I/O PCMCIA
Card.
Output Enable for Memory PCMCIA
card.
Write Enable for Memory PCMCIA
card.
When this signal is LOW, memory
access is restricted to Attribute memory
space.
Card Detect Input 1 and 2
*VS1, VS2
*BVD1

Input
Input
When this signal is LOW, memory
access is limited to Attribute memory
space.
The battery voltage detect input 1 on the
memory PCMCIA Card. During normal
access for I/O, this signal must be kept
LOW.
Input
In I/O Card, this signal is used as Card
Status Change or Ring Indicate input
according to the Host Bus Adapter’s
configuration setting.
The battery voltage detect input 2 on the
memory PCMCIA Card.
Input
In I/O Card, this signal is used as
Speaker input.
Ready/nBusy input on the memory
PCMCIA Card.
In I/O Card, this signal is used as
Interrupt Request signal.
