• Point 2: SpePINPos (7 bits) >= SpePinLenPos (2 bits) + SpePINSize (4 bits)
• Point 3: SpePINLen (9h) – SpePinPos (7 bits)[act as 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.
