Description
HA[8:0]
Input
An attribute address range of 512 even bytes accesses is supported. An I/O space of 4 words is used (i.e.
HA[2:0] is used and HA[8:0] is not used).
HD[15:0]
Bidirectional
Attribute memory is standardized to even byte accesses only. Input/Output memory is defined as word ac-
cesses only (to maximize packet transfer rates).

Output

HRST
Input
The card reset is provided by HRST. HRST must be asserted for a period of time from power up to allow the
oscillator to settle. The MSM7712 is set to a default state while HRST is asserted and SCK is available. From
HRST being deasserted the MSM7712 must download the CIS table from the E
reset procedure is considered complete.

HIREQN
Output
HIREQN operates as the RDY/BSY line until the card is configured and hence remains low until the reset pro-
cess is complete (as defined in the PCMCIA standard). Once reset is complete, HIREQN functions as a level-
sensitive interrupt to the host.
HWAITN
Input
Wait states are potentially required when the host accesses the shared memory (to transfer packet data). In-
ternal registers require no wait states.
