1.3 ENTRY MODE SETTING
When data is written in and read from the DDRAM, CGRAM, ICONRAM, or the ICON BLINK RAM in accordance with the ID,
set ID=1 [increment] or ID=0 [decrement] of the selected RAM address counter.
S
determines whether or not the whole display shifts during the write in the DDRAM. The display shifts left when ID=1,
and shifts right when ID=0.
