Note
You can have between 1 and 16 steps in the Configuration/Profile table, Profile block 0.

The offset of Profile block 1 and subsequent blocks is variable and dependent upon the number of
1
steps configured in the largest profile. The offset is determined by the following formula:
Offset of Profile block x = CB_LEN + IB_LEN + (x * PF_LEN)
