The screen actually displayed is not modified.This function is usable only if the TEXT_ATTRIBUT mode is not used. It only copies the GRAPHIC plan.Attributes 1 and 2 : MSB and LSB addressee corresponding to the beginning of the EEPROM zone reservedat this screen (multiple of $40).User Note :<strong>SERIAL</strong>_<strong>LCD</strong>G Specifications Version 1.1 - April 2006 Page 30 of 37Last printed 03/06/2006 12:37
