I know how to set up 8 bit connection.
I want to learn how to transfer 8 or 16 bits with 4 bit connection.
Because say

LCDOUT $FE,0,1

is NOT equal (in terms what I see on display)

to

LCDOUT $FE,0
LCDOUT $FE,1

So I guess, on each LCDOUT statement, there's something special made to display. So I'm interested exactly what happens.
