This bit is used to determine the internal state of the Rdy/-Bsy signal. This bit may be used to determine the
state of the Ready/-Busy as this pin has been reallocated for use as Interrupt Request on an I/O card. When
written, this bit acts as a mask for writing the corresponding bit CRdy/-Bsy.
This bit is always zero (0) since the CompactFlash Memory Card does not have a Write Protect switch. When
written, this bit acts as a mask for writing the corresponding bit CWProt.
This bit acts as a mask for writing the corresponding bit CRdy/-Bsy.
This bit when written acts as a mask for writing the corresponding bit CWProt.
This bit is reserved for future standardization. This bit must be set to zero (0) by the software when the
register is written.
This bit indicates the drive number of the card if twin card configuration is supported.
The socket number is ignored by the CompactFlash Memory Card.
