How about the PIN management?
Because it is Left and BCD arrangement
PIN (Byte)
Original 00 24 00 01 09 57 30 30 30 30 30 30 30 30h
Input 12 34 56 78 0h
Result PIN 00 24 00 01 09 59 12 34 56 78 00 30 30 30h
The whole APDU in byte format will be:
00 24 00 01 09 59 12 34 56 78 00 30 30 30h
If arrangement is Right:
bmFormatString change to=8Dh
00 24 00 01 08 59 30 30 30 31 23 45 67 80h
12.12. Modification Example 4
bConfirmPIN Bit1 = 1
(Current/Old PIN entry requested)
System unit is bit.
