Bit(s)

Description

 

 

Changed

Indicates that either CREADY (D5) or CWPort (D4) of the Pin

 

Replacement register is set. Additionally, this bit changes state

 

as the Powerdown (D2) bit changes.

 

 

SigChg

Outputs the inverse state of the Changed bit to the hardware

 

interface signal STSCHG# at the card interface.

 

 

Iois8

Informs the host of the valid data bus width for the operations in

 

progress:

 

• 0 = 16-bit data transfer

 

• 1 = 8-bit data transfer

 

 

PwrDwn

Indicates the state of the Card, which is either operating -0 or

 

powerdown mode 1. During powerdown mode, no commands

 

are accepted. Additionally, the host may not initiate a

 

powerdown request when the card is busy via the Status

 

register or the Hardware RDY/BSY pin.

 

 

Int

Indicates the inverse of the IREQ# status signal.
