Description
GAM375-
BitOrder B8 Boolean 1 1 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 bit order applies to all
operations, including the
ATR returned from the
Power Up command.
GAM375
Counter Lowest
Address B9 Dword 1 8 Get/Set
This is the lowest address
that will be accepted in an
Erase Counter command.
GAM375
Counter Highest
Address BA Dword 1 11 Get/Set
This is the highest address
that will be accepted in an
Erase Counter command.
Data is sent and received as bytes. When the GAM375-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 72, the card will end up with the following bit pattern on the card:
Address
72……….80……….88…….95
11001100 01000100 10001000
When the GAM375-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 72, the
card will end up with the following bit pattern on the card:
Address
72……….80……….88…….95
00110011 00100010 00010001
Power Up
The Power Up command is issued as with Microprocessor cards and can get same Result Codes.
When the Result Code indicates an Error or Warning, the Primary Status of the CondRpt
Property will never be 0x03.
