10 / 43 page ST8009 V1.1 10/43 2006/11/1 XDISPOFF The switch for turn on or turn off the LCD display The input signal is level-shifted from logic voltage level to LCD drive voltage level, and controls the LCD drive circuit. When set to VSS level "L", the LCD drive output pins (CS0-CS95) are set to level VSS. When set to "L”, the contents of the shift register are reset to not reading data. When the /DISPOFF function is canceled, the driver outputs non-select level (V1 or V4), and the shift data is read at the next falling edge of the LP. At that time, if /DISPOFF removal time does not correspond to what is shown in AC characteristics, the shift data is not read correctly. Table of truth-values is shown in "TRUTH TABLE" in Functional Operations. FR AC signal input pin for LCD drive waveform The input signal is level-shifted from logic voltage level to LCD drive voltage level, and controls the LCD drive circuit. Normally it inputs a frame inversion signal. The LCD drive output pins' output voltage levels can be set using the shift register output signal and the FR signal. Table of truth-values is shown in "TRUTH TABLE" in Functional Operations. CS0 ~CS95 LCD drive output pins Corresponding directly to each bit of the shift register, one level (V0 V1, V4, or VSS) is selected and output. Table of truth-values is shown in "TRUTH TABLE" in Functional Operations. EIO1, EIO2 Shift data Input/output pins for shift register EIO1 is output pin when L/R is at VSS level “L”, EIO1 is input pin when L/R is at VDD level “H” When L/R register =’1’, EIO1 is used as input pin, it will be connect to FLM. When L/R register =’0’, EIO1 is used as output pin, it won’t be connect to FLM. EIO2 is input pin when L/R is at VSS level “L”, EIO1 is output pin when L/R is at VDD level “H” When L/R register =’1’, EIO2 is used as output pin, it won’t be connect to FLM, When L/R register =’0’, EIO2 is used as input pin, it will be connect to FLM Refer to “RELATIONSHIP BETWEEN THE DISPLAY DATA AND LCD DRIVE OUTPUT PINS” in Functional Operations. CAP1- DC/DC voltage converter. Connect a capacitor between this terminal and the CAP2- terminal. CAP1+ DC/DC voltage converter. Connect a capacitor between this terminal and the CAP1- terminal.
