8.3 Pin Replacement Register (Address 204H in Attribute Memory)
CRDY/BSY# This bit is set to one (1) when the bit RDY/BSY# changes state. This bit can also be
written by the host.
CWProt
This bit is set to one (1) when the RWprot changes state. This bit may also be written by
the host.
RDY/BSY#
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#.
WProt:
This bit is always zero (0).
When written, this bit acts as a mask for writing the corresponding bit CWProt.
MRDY/BSY# This bit acts as a mask for writing the corresponding bit CRDY/BSY#.
MWProt:
This bit when written acts as a mask for writing the corresponding bit CWProt.
8.4 Socket and Copy Register (Address 206H in Attribute Memory)
This register contains additional configuration information. This register is always written by the system before writ-
ing the card’s Configuration Index register.
Reserved
This bit is reserved for future standardization. This bit must be set to zero (0) by the
software when the register is written.
Drive #
This bit indicates the drive number of the card for twin card configuration.
Twin card configuration is currently not supported
X
The socket number is ignored by the CompactFlash card.
