is on and stable, RST is Inactive)

When the bmCommandStatus field is 0 indicating the command processed without error or
when the bmCommand field is an RFU value, then the slot’s error register is RFU.
When the bmCommandStatus field is 1 indicating the command failed, then the slot’s error
register is set with a signed 8-bit value.
When the bmCommandStatus field is 2, indicating a time extension is requested, then the
slot’s error register contains the multiplier value of BWT when the protocol is T=1 or the
multiplier value of WWT when the protocol is T=0.
Command processed without error: Slot Status register = 0xh
Command failed (error code provided by the error register): Slot Status register = 4xh
Time extension is requested (slot error register = time multiplier): Slot Status register = 80h
x = 0
: Card present and active
x = 1
