LUTU

LUT Use

Class

Lookup table memory management

Description

Loads the lookup table hardware in accordance with the buffer contents.

The LUTU? query returns either a lookup table memory location

location

or 0. If the lookup

table currently in the hardware matches that originally loaded (using the LUTL command)

from a lookup table memory location, then the matching lookup table memory location

location

is returned. Otherwise, if the hardware contents have changed since either an

LUTR or LUTL command has been issued, then LUTU? query returns 0.

Command syntax
