No operation.
Move data in source location to destination location. Source location is
bits 4 through 7, and destination location is bits 0 through 3. Source
locations and destination locations must be of the same type. For
example, commands that move data from the VCOM registers to the
gamma registers and vice-versa are not valid, and the I
issues a NACK.
