Three state I/O common terminal. DB0 (LSB) ... DB7 (MSB) /RD(E) When connected to an 8080 MPU, it is active LOW. This pad is connected to the RD signal of the 8080MPU, and the NT7532 data bus is in an output status when this signal is "L" When connected to a 6800 Series MPU, this is active HIGH. This is used as an enable clock input of the 6800 series MPU /WR(R/W When connected to an 8080 MPU, this is active LOW. This terminal connects to the 8080 MPU WR signal. The signals on the data bus are latched at the rising edge of the WR signal. When connected to a 6800 Series MPU, this is the read/write control signal input terminal. When W R/ = "H": Read When W R/ = "L": Write Data or Instruction. 26 A0 A0 = H DB<0:7>: Display RAM data A0 = L DB<0:7>: Instruction data 27 /RES 14 16 RES I When RES is set to "L", the settings are initialized. The reset operation is performed by the RES signal level 28 /CS1 This is the chip select signal. When CS1="L", then the chip select becomes active, and data/command I/O is enabled.

Contrast ratio is calculated by the following formula when the output voltage (Fig.2-a, positive type; Fig 2-b,negative type) is obtained from the next electro-optical test system (Fig.1) B. Conditions of Testing: Accord to the LCD s driving method and operating voltage (Vop) C. The formula: Photometer output voltage when non-select waveform is applying Contrast ratio = ----------------------------------------------------------------------------------- (positive type ) Photometer output voltage when select waveform is applying Photometer output voltage when select waveform is applying Contrast ratio = ----------------------------------------------------------------------------------- (negative type ) Photometer output voltage when non-select waveform is applying D. Test system: Fig. 1 Note 2: Response time A. Rise time is defined as the time required for the transmission to change from 90% to 10%. B. Fall time is defined as the time required for the transmission to change from 10% to 90%. C. On time is defined as the time required for the transmission to change from 100% to 10%. D. Off time is defined as the time required for the transmission to change from 10% to 100%.
