Product data sheet Rev. 04 — 4 March 2008 50 of 65 NXP Semiconductors PCF2113x LCD controllers/drivers when combined with display shift operation. Since the display shift operation changes display position only and the DDRAM contents remain unchanged, display data entered first can be displayed when the ‘return home’ operation is performed. Table 22. 8-bit operation, 1-line display example; using internal reset (character set ‘A’) Step Instruction Display Operation RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 1 power supply on (PCF2113x is initialized by the internal reset) initialized; no display appears 2 function set sets to 8-bit operation, selects 1-line display and VLCD = VA 0000110000 3 display control turns on display and cursor; entire display is blank after initialization 0000001110 4 entry mode set sets mode to increment the address by 1 and to shift the cursor to the right at the time of the write to the DDRAM/CGRAM; display is not shifted 0000000110 5 ‘write data’ to CGRAM/DDRAM writes ‘P’; the DDRAM has already been selected by initialization at power-on; the cursor is incremented by 1 and shifted to the right 1001010000P 6 ‘write data’ to CGRAM/DDRAM writes ‘H’ 1001001000PH 7 to 10 : writes ‘ILIP’ : 11 ‘write data’ to CGRAM/DDRAM writes ‘S’ 1 0 0 1 0 1 0 0 1 1 PHILIPS 12 entry mode set sets mode for display shift at time of write 0 0 0 0 0 0 0 1 1 1 PHILIPS 13 ‘write data’ to CGRAM/DDRAM writes space 1 0 0 0 1 0 0 0 0 0 HILIPS 14 ‘write data’ to CGRAM/DDRAM writes ‘M’ 1 0 0 1 0 0 1 1 0 1 HILIPS M 15 to 19 : writes ‘ICROK’ : 20 ‘write data’ to CGRAM/DDRAM writes ‘O’ 1 0 0 1 0 0 1 1 1 1 MICROKO 21 cursor/display shift shifts only the cursor position to the left 0 0 0 0 0 1 0 0 0 0 MICROKO 22 cursor/display shift shifts only the cursor position to the left 0 0 0 0 0 1 0 0 0 0 MICROKO 23 ‘write data’ to CGRAM/DDRAM writes ‘C’ correction; the display moves to the left 1001000011ICROCO 24 cursor/display shift shifts the display and cursor to the right 0 0 0 0 0 1 1 1 0 0 MICROCO |
