a) 8 bit access mode
b) 16 bit access mode
selected ( WIN =”1” ), address is increased as following loop.
And when X, Y auto increment mode operating, window access is possible.
The increment operating is as above description.
Two-byte access is done by single RAM access.
Address is increased after access.
X address is increased as (00
X address is increased to Max
You should set X address, Y address in sequence, anything else is forbidden.
