Function Specifications 4.1 Adjusting the Display Contrast A Variable-Resistor must be connected to the LCD module for providing a reference to V0. Adjusting the VR will result the change of LCD display contrast. The recommended value of VR is 25k to 50k 4.2 Resetting the LCD module The LCD module should be initialized by hardware reset, using /RES terminal. 4.3 Jumper Functions 4.3.1 Interfacing Setting Jumper Function Description JP3 JP6 Open Close CNF3=L, 8080 mode selected <default> Close Open CNF3=H, 6800 mode selected 4.3.2 Clock Divider Setting Jumper Function Description JP1 JP2 JP4 JP5 Open Open Close Close 1/4 clock divider Close Open Open Close 1/8 clock divider<default> Open Close Close Open 1/16 clock divider 4.4 Display Pixel Map 1,1 (D7) 2,1 (D6) 3,1 (D5) 4,1 (D4) 5,1 (D3) - - - - - - 316,1 (D4) 317,1 (D3) 318,1 (D2) 319,1 (D1) 320,1 (D0) 1,2 (D7) 2,2 (D6) 3,2 (D5) 4,2 (D4) 5,2 (D3) - - - - - - 316,2 (D4) 317,2 (D3) 318,2 (D2) 319,2 (D1) 320,2 (D0) 1,3 (D7) 2,3 (D6) 3,3 (D5) 4,3 (D4) 5,3 (D3) - - - - - - 316,3 (D4) 317,3 (D3) 318,3 (D2) 319,3 (D1) 320,3 (D0) : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : 1,238 (D7) 2,238 (D6) 3,238 (D5) 4,238 (D4) 5,238 (D3) - - - - - - 316,238 (D4) 317,238 (D3) 318,238 (D2) 319,238 (D1) 320,238 (D0) 1,239 (D7) 2,239 (D6) 3,239 (D5) 4,239 (D4) 5,239 (D3) - - - - - - 316,239 (D4) 317,239 (D3) 318,239 (D2) 319,239 (D1) 320,239 (D0) 1,240 (D7) 2,240 (D6) 3,240 (D5) 4,240 (D4) 5,240 (D3) - - - - - - 316,240 (D4) 317,240 (D3) 318,240 (D2) 319,240 (D1) 320,240 (D0) Pixel mapping (Top View) Note: *1. Based on the top view of the LCD module, the 1, 1 (x, y) pixel is the upper-left pixel; the 320, 240 (x, y) pixel is the lower-right pixel. *2.
