SUM[a:b] = [Sum of locations a to b inclusive]
SUM_ID = User ID locations masked by 0xF then made into a 16-bit value with ID0 as the Most Significant
nibble.
For example, ID0 = 0x1, ID1 = 0x2, ID2 = 0x3, ID3 = 0x4, then SUM_ID = 0x1234.
*Checksum = [Sum of all the individual expressions] MODULO [0xFFFF]
+ = Addition
& = Bitwise AND
Checksum shown assumes that SUM_ID contains the unprotected checksum.
