11.4. Verification Example 2
System unit is bit.
abPINApdu = 00 20 00 01 08 57 A5 30 30 30 30 30 30h
After Lc (08h), the first 11 bits (01010111 101) is control character.
bmFormatString=59h
SpePinPos=11 bits because bmFormatString bit 7 = 0
SpeLeftRight=Left
SpePINTyp=BCD
bmPINBlockString=48h
SpePINSize=4 bits
SpePINLen=8 bytes
bmPINLengthFormat=06h
SpePINLenPos=6 bits
wPINMaxExtraDigit=0108h
SpePinMax=08h
SpePinMin=01h
PIN Input = 1 2 3 4 5

How about the the PIN management?
Because it is Left and BCD arrangement.
