CO = 0 :mixed mode CO = 1 : full page mode C1 = 0 : the character background is controlled by BE (see character word description) C1 = 1 : all displayed character backgrounds are disabled C2 = 0 :display off C2 = 1 : display on C3 = 0 : the characters are colored according to the character attribute and the color register values (i.e. CBACKG and CBORD) C3 = 1 : the character foreground, border and background colors are all set to the character attribute value (see paragraph l.2). This option is mainly intended for full page mode CVBS or Y/C output C4 = 0 :1.0 second blinking period C4 = 1 : 0.5 second blinking period C[6:5] = 00 : blinkingoff 01 : 0.75 blinking duty cycle 10 : 0.5 blinking duty cycle 11 : 0.25 blinking duty cycle

After writing the first set of data up t0 2112 byte into the selected page register, Dummy Page Program command (11h) instead of actual Page Program command (10h) is inputted to finish data-loading of the first plane. Since no programming process is involved, R/B remains in Busy state for a short period of time(tDBSY). Read Status command (70h) may be issued to find out when the device returns to Ready state by polling the Ready/Busy status bit(l/0 6). Then the next set of data for the other plane is inputted after the 81h command and address sequences. After inputting data for the last plane, actual True Page Program(lOh) instead of dummy Page Program command (11h) must be followed to start the programming process. The operation of R/B and Read Status is the same as that of Page Program. Althougth two planes are programmed simultaneously, pass/fail is not available for each page when the program operation completes. Status bit of 110 0 is set to "1" when any of the pages fails. Restriction in addressing with Two-Plane Page Program is shown is Figure14.
