command stops the scrolling alphanumeric message if the cursor position is
on the top line when this command is sent.
Test (0F) <SI>

Purpose:
Causes the first 40 characters in the currently selected character set to be
displayed once. At the end of the test, a test pattern is written that turns all
pixels ON. At the end of the test, the display is cleared and is reset to the
power-on state as described at “Reset (1F) <US>” on page A-7.

Purpose:
Changes the cursor position. The byte that follows the command byte
indicates the character position where the next data-string write operation is
to start. Any values greater than X'27' are ignored and the cursor position
remains unchanged. This command stops the scrolling alphanumeric
message if the cursor position is on the top line when this command is
sent.

Normal-display control mode (11) <DC1>
11
Purpose:
Sets normal display-control mode (DC1) and permits data to be written to
either line. After a character is written, the cursor moves one position to the
right. When the display position is at the last position of the top line, the
cursor moves to the first position of the bottom line. When the display
position is at the last position of the bottom line, the cursor moves to the
first position of the top line. The display remains in DC1 mode until a DC2
mode command is issued, a reset command is issued, or power is removed
from the display.
