In variable mode, the CE and INC ports are used to manually increment and decrement the delay-line tap per tap (INC/DEC increments or decrements one tap at a time). The tap delay increments by setting CE = 1 and INC = 1, or decrements by CE = 1 and INC = 0. If the delay line incremented or decremented outside its valid values (that is, past the 32nd tap), the tap line wraps around back to the smallest or largest tap value.
