bMsgIndex:
00h: LCD will display “Enter PIN:”
Any other values will raise an error.
If the data structure format error, the ACR83 will give “6B 80h.”
For the system unit is bit (bmFormatString bit 7=0). The APDU formatting is total different with system
unit is byte (bmFormatString bit 7=1).

Check points in implementing the PIN Verification Data Structure:
• SpePINLen 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
11.2. Error Checking (Byte)
Check points in implementing the PIN Verification Data Structure:
• Lc must equal to SpePINLen + SpePINPos
• 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
Verification system unit is byte.
