Okay, I belive you.
Anyway - the qustions are open:
- does disabling of EEPROM Column Latches not discard previous bytes wrote into it? As I understand from your answer, it does not. So what is the way to discard prepared bytes in the Column Latches? May it be done by wrong command sequence, for example 0x50 0x60, yeah?
- what is the more important bit: EEE or EXTRAM? by other words, if I enable mapping of both EEPROM and XRAM and then do MOVX so which memory be used? I think it should be EEPROM, isn`t it?

Thank you!
