• SpePINLen – SpePINPos 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

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
• SpePINLen – SpePINPos 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
