Clearing EVFU Memory

Use one of the three following actions to clear (reset) the EVFU Memory.

Send only the Start Load and End Load codes (no channel assignment

data).

Send an odd number of EVFU characters (channel assignment data)

(detected after the End Load code is received). Remember, two data

bytes are required per line.

Send a second Start Load code, which will result in reinitializing the

EVFU memory routine.
