PIN Input = 1 2 3 4 5 6 7 8 0
• Point 1: SpePINLen (9) equal to SpePINLen (8) + SpePinPos (1)
• Point 2: SpePINPos (1 Byte) >= SpePinLenPos (4 bits) + SpePINSize (4 bits)
• Point 3: SpePINLen (9) – SpePinPos (1 Byte) >=[SpePinMax (0Ah) * 4bits(BCD)] = 5 Bytes
: 8 Bytes >=5 Bytes
• Point 4: SpePinMax (0Ah) > SpePinMin (01h)
• Point 5: SpePinMax (0Ah) < =10h
• Point 6: SpePinMin (01h) >= 01h

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