Variables
|
Name |
Description |
|
Historical bytes sent by Smart Card | |
|
Number of Historical bytes present | |
|
length of ATR data sent by smart card | |
|
ATR data sent by smartcard. | |
|
Smart Card Error type is stored in this variable | |
|
PPS Response Bytes | |
|
Length of PPS Response | |
|
TA1 determines the clock-rate conversion factor F & bit-rate-adjustment factor D | |
|
TA2 determines whether the smart card will operate in specific mode or negotiable mode following the ATR | |
|
TA3 conveys the Information Field Size Integer (IFSI) for the smart card. | |
|
TB1 conveys information on the smart card's programming voltage requirements. | |
|
TB2 conveys PI2, which determines the value of programming voltage required by the smart card. The value of PI1 in TB1 is superceded when TB2 is present | |
|
TB3 indicates the value of the Character Waiting Time Integer (CWI) and Block Waiting Time Integer (BWI) used to compute the Character Waiting Time (CWT) and Block Waiting Time (BWT). | |
|
TC1 determines the extra guard time to be added between consecutive characters sent to the smart card from the terminal. | |
|
TC2 is specific to protocol type T=0. TC2 conveys work waiting-time integer (WI) that determines the maximum interval between the leading edge of the start bit of any character sent by the smart card and the leading edge of the start bit of the previous character sent either by the card or the reader | |
|
When TC3 is present, it indicates the type of block-error detection to be used. When TC3 is not present, the default longitudinal redundancy check (LRC) is used. | |
|
TD1 indicates if any further interface bytes are to be transmitted, and if so, which protocol will be used. | |
|
The TD2 character has the same function as the TD1 character. | |
|
TD3 indicates interface bytes similar to that of TD1 & TD2 |
