SLE 4404 MEMORY CARD CONTROL.
This section defines the commands needed to control the SLE 4404 card type. There are many
cards available that are similar to the SLE4404, and this device will support many of them. It is
assumed that the user has access to the manufacturer’s specifications for this type of card.
This section will address the memory available on the card as a file. For compatibility of
terminology with ISO 7816-4, we will assume that the memory is in an “implicitly selected” file
after we power up the card.
Properties
With the addition of the SLE 4404 support comes a property the user may need access to.

Description
4404-BitOrder AE Boolean 1 0 Get/Set
A value of 0 causes the least
significant bit of each byte to
be sent or received first. A
value of 1 causes the most
significant bit of each byte to
be sent or received first.
This property DOES NOT
APPLY to the Power Up
command, which always
reads the bytes least
significant bit first.
Data is sent and received as bytes. When the 4404-BitOrder property is set to 0, the least
significant bit of each byte represents the lowest addressed bit on the card. If we write the bytes
33 22 11 to a card at address 73, the card will end up with the following bit pattern on the card:
Address
73……….81……….89…….96
11001100 01000100 10001000
When the 4404-BitOrder property is set to 1, the most significant bit of each byte represents the
lowest addressed bit on the card. If we write the bytes 33 22 11 to a card at address 73, the card
will end up with the following bit pattern on the card:
