Description
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.
Outputs the inverse state of the Changed bit to the hardware
interface signal STSCHG# at the card interface.
Informs the host of the valid data bus width for the operations in
progress:
• 0 = 16-bit data transfer
• 1 = 8-bit data transfer
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.
Indicates the inverse of the IREQ# status signal.
