Check points in implementing the PIN Modification Data Structure:

SpePINLen + SpeOffsetNew must be equal to Lc

SpePINPos must be equal or larger than SpePINLenPos + SpePINSize

SpePINLenSpePINPos must be larger or equal to SpePinMax(if BCD, need multiple 4)

SpePinMax must be equal or larger than SpePinMin

SpePinMax cannot be larger than 16 digits because LCD one row only have 16 digits

SpePinMin must be equal or larger than 1

bConfirmPIN = 00h (if bConfirmPIN = 00h, the bNumberMessage must equal to 01h, 00h)
Enter the New PIN once.

bmFormatString=39h

SpePinPos=7 bits because bmFormatString bit 7 = 0
SpeLeftRight=Left
SpePINTyp=BCD

bmPINBlockString=49h

SpePINSize=4 bits
SpePINLen=9 bytes


bmPINLengthFormat=02h

SpePINLenPos=2 bits
