Appendix B. Memory Card Support
99
Data is sent and received as bytes. When the GAM326-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 GAM326-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.
APDU Exchange command
The APDU Exchange Command is used to control logical operations of the card between Power
Up and Power Down. The APDU is issued as with Microprocessor cards. The Result Codes are
the same as for Microprocessor cards. When the Result Code indicates an Error or Warning, the
Primary Status of the CondRpt Property will never be 0x03.
Two SW1/SW2 Status Codes may apply to any APDU:
SW1/SW2 Meaning
6E00 CLA Not Supported
6D00 INS Not Supported
Read Binary APDU
Command APDU:
CLA INS P1 P2 Le
00 B0 xx Adr Len
CLA is always 00
INS is always B0
P1 is ignored
P2 is the address where the read will start
Le is the number of bytes to read, 0 will read 256 bytes
