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
