16x2 LCD how to access symbols with ROM Code: A02

Here is a link for original hitachi datasheet:

I've found in awesome thread:
http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1286905796/5

There are two tables of characters in it, page 17 and page 18. By sending char codes from 0 to 255 I can access characters from first table ("ROM Code: A00"), is it possible to access characters from the second ("ROM Code: A02")? Or these are variants of two possible ROMs and concrete display will have one of them?

I'm using CrystalLibrary in 4bit mode.

Thanks in advance!

Or these are variants of two possible ROMs and concrete display will have one of them?

Yes.

Thanks, Don!

Have you seen models with ROMs different from this two? Or I can just ask in a store for A00 or A02?

For googlers: in datasheet (link above) on the page #2 (Ordering Information) there is a list of different models with different ROMs.

Or I can just ask in a store for A00 or A02?

No they won't know what you mean. You have to give the order code given in the data sheet.

Thank you for the replies.

Does text LCD with customizable character generator or with more than 256 symbols table exists?

Maybe for such tasks the graphics display is the only way?
