ATR MAP STRUCTURE – MICROPROCESSOR CARDS ONLY
The ATR Map structure is retrieved by reading property 40 (Hex). This property gives a detailed
analysis of the ATR as received from the card. The structure is as follows:
Bytes Meaning
0
TS character, as received from the card
1
T0 character, as received from the card
2
TA1 Present? 0 = no, 1 = yes
3 TA1
value
If TA1 Present = 1, as received from the card
If TA1 not present, set to 0x11
4
TB1 Present? 0 = no, 1 = yes
5 TB1
value
If TB1 Present = 1, as received from the card
If TB1 Present = 0, set to 0x25
6
TC1 Present? 0 = no, 1 = yes
7 TC1
value
If TC1 Present = 1, as received from the card
If TC1 Present = 0, set to 0X00
8
TD1 Present? 0 = no, 1 = yes
9 TD1
value
If TD1 Present = 1, as received from the card
If TD1 Present = 0, ignore the value
10
TA2 Present? 0 = no, 1 = yes
11 TA2
value
If TA2 Present = 1, as received from the card
If TA2 Present = 0, ignore the value
12
TB2 Present? 0 = no, 1 = yes
13 TB2
value
If TB2 Present = 1, as received from the card
If TB2 Present = 0, ignore the value
14
TC2 Present? 0 = no, 1 = yes
15 TC2
value
If TC2 Present = 1, as received from the card
If TC2 Present = 0, set to 0x0A
16
TD2 Present? 0 = no, 1 = yes
17 TD2
value
If TD2 Present = 1, as received from the card
If TD2 Present = 0, ignore the value
18
TCK Present, 0 = no, 1 = yes
19 TCK
value
If TCK Present = 1, as received from the card
If TCK Present = 0, ignore the value
20
Number of history bytes received from the card
21 – 36
History bytes as received from the card. The bytes start at position 21 and continue
for the count specified in location 20. Ignore additional bytes
37
T=0 Available? 0 = no, 1 = yes
38
T=1 Available? 0 = no, 1 = yes
39
TAi for T=1 Present? 0 = no, 1 = yes
