When data set up in the internal registers are read
out, set the read address allotted to each register
by this command before executing the read
command of the internal registers.
For example, when the data of the command
register in the display control (1) are read out, set
the values of (RA3, RA2, RA1, and RA0 ) = 8
H
.
Refer to the functional description of each
command or the list of commands for the read
