Bits SC and RL: Curs_disp_shift moves the cursor position or the display to the right or
left without writing or reading display data. This function is used to correct a character or
move the cursor through the display.
In 2-line displays, the cursor moves to the next line when it passes the last position (40) of
the line. When the displayed data is shifted repeatedly all lines shift at the same time;
displayed characters do not shift into the next line.
The address counter content does not change if the only action performed is shift display
(SC = 1) but increments or decrements with the shift cursor (SC = 0).

set CGRAM address
Set_CGRAM: Sets the CGRAM address bits ACG[5:0] into the address counter. Data can
then be written to or read from the CGRAM.
Remark: The CGRAM address uses the same address register as the DDRAM address.
This register consists of 7 bits. But with the Set_CGRAM command, only bit 5 to bit 0 are
set. Bit 6 can be set using the Set_DDRAM command first, or by using the auto-increment
feature during CGRAM write. All bits 6 to 0 can be read using the BF_AC instruction.
When writing to the lower part of the CGRAM, ensure that bit 6 of the address is not set
(e.g. by an earlier DDRAM write).
