Check points in implementing the PIN Modification Data Structure:
• SpePINLen + SpeOffsetNew + SpePINPos must be equal to Lc
• SpeOffsetNew >= SpeOffsetOld + SpePINPos + SpePINLen
• 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
