•
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
