When /CS1="L" and CS2=”H”, MPU interface is available. When the chip select pin is inactive (other /CS1 and CS2 condition), D7 to D0 are high impedance (invalid) and input of A0, /RD, or /WR inputs are not effective.

Serial Interface (SPI) When serial mode (PS = "L"), D6 (SCK) is used as serial clock input pin, D7 (SDI) is used as serial data input pin, D5 (SDO) is used as serial data output pin. When the LSI is active (/CS1=”L”, CS2=”H”), serial data input (D7), serial clock input (D6) inputs and serial data output (D5) are enabled. The 8-bit shift register and 3-bit counter are reset to the initial condition when the chip is not selected. The data input/output from SDI/SDO terminal is MSB first as in the order of D7, D6…D0, and is latched at the rising edge of the serial clock SCK. Serial input data is display data when A0="H" and instruction when A0="L". The A0 input is read in and identified at the rising edge of the (8 x n) serial clock pulse. Since the clock signal (D6) is easy to be affected by the external noise caused by the line length, the operation check on the actual machine is recommended. /CS1 CS2 SCK (D6) SDI (D7) D7 SDO (D5) D6 D7 D5 D6 D4 D5 D3 D4 D2 D3 D1 D2 D0 D1 D7 D0 D7 A0 Figure 4 Serial Interface Signal Chart A0 /WR (R/W) D7 (SDI) D5 (SDO) 0 0 Instruction Write Status Read 0 1 Invalid Status Read 1 0 Display Data Write Status Read 1 1 Invalid Display Data Read Product Specification (V1.0) 12.28.2005 13 EPL09060 9 COM/60 SEG LCD Driver Parallel Interface (8-bit Length) Parallel mode (8-bit length): When parallel input is selected (PS = ”H”), D0~D7 can be connected directly to the 80-series or 68-series MPU by setting the C86 pin to high or low.

When writing data from the MPU to the DDRAM, data is automatically transferred from the bus holder to the DDRAM. When reading data from the DDRAM to the MPU, the data for the initial read cycle is stored in the bus holder (dummy read) and the MPU reads this stored data from the bus holder for the next data read cycle. 14 • Product Specification (V1.0) 12.28.2005 EPL09060 9 COM/60 SEG LCD Driver Register Initial Display Line Line Counter Decoder D is p la y D a t a R A M Line Address Decoder Low Address Register Page Address 7.2.1 Display Data RAM (DDRAM) C o lu m n A d d r e s s D e c o d e r C o lu m n A d d r e s s C o u n t e r C o lu m n A d d r e s s R e g is t e r Figure 6 Display Data RAM Diagram The display data RAM (DDRAM) stores pixel data for the LCD. It is a 43-row × 102column addressable array. It is possible to access any required bit by specifying the page address and the column address. The 43 rows are divided into five pages of eight lines, one page with two lines (D0, D1) and the seventh page with a single line (D0 only). Each bit in the Display Data RAM corresponds to each pixel of the LCD panel. Each bit in the Display Data RAM corresponds to each pixel of the LCD panel and controls the display by applying the following bit data.

But the EPL09060 have real output common pins COM0~7 and COMI, the others are invalid. Initial Display Line Register The initial display line register assigns a DDRAM line address which corresponds to COM0 by using the “Initial display line set” instruction. It is used not only for normal display but also for vertical display scrolling and page switching without changing the contents of the DDRAM. However, the 9th address for the icon display cannot be assigned for the initial display line address. Line Counter The line counter provides a DDRAM line address. It initializes its contents at the switching of frame reversal signal (FR (internal)), and also counts-up in synchronization with the common timing signal. 16 • Product Specification (V1.0) 12.28.2005 EPL09060 9 COM/60 SEG LCD Driver Column Address Counter The column address counter is an 8-bit preset counter which provides a DDRAM column address, and is independent of page address register. It will increment (+1) the column address whenever “display data read” or “display data write” instructions are issued. However, the incrementing of column address is stopped at column address 65H. The count-lock will be released by the “column address set” instruction again. The counter can inverts the correspondence between the column address and segment driver direction by means of “ADC select” instruction.

The boosting magnitude of the internal booster circuit is selected by means of the capacitor connection (Refer to Figure 16 below). The internal oscillator is required to be operating when using this converter, since the divided signal provided from the oscillator is used for the internal timing of this circuit.

Since VOUT is the operating voltage of the operational-amplifier circuits, it is necessary to be applied either internally or externally. For Equation 1, V0 is determined by Ra, Rb and VEV. Ra and Rb are connected internally or externally through the IRS pin. VEV which is the electronic volume voltage, is determined by Equation 2, where the parameter α is the value selected by the instruction "Set Contrast Control Mode," within the range 0 to 63.

Using Internal Resistors, Ra and Rb (IRS = "H") When the IRS pin is “H”, resistor Ra is connected internally between VR pin and VSS, and Rb is connected between V0 and VR.

For optimum bias level, BL can be calculated using the following equation: BL = 1 Duty ratio + 1 Changing the bias system from the optimum will have an effect on the contrast and viewing angle. The LCD Bias affects the display quality. But to reduce the current consumption, an unsuitable bias may be selected. Hence, the LCD Bias could be selected by “Select LCD bias” instruction. 7.4.4 Oscillator The on-chip RC type oscillator provides the display clock and voltage converter timing clock. It has low power consumption and its frequency is nearly independent of VDD. When “CLS”=”H”, the oscillator circuit is enabled. When CLS=”L”, the oscillator is stopped, and the oscillator clock has to be input to the OSC pin.

The frame frequency (fFM) is derived from the RC circuit’s oscillation frequency (fOSC) by giving it an appropriate value. The relationship between the oscillation frequency (fOSC), display clock frequency (fCL) and the frame frequency (fFM) is shown below. The fOSC could be selected from an internal or external oscillator via the CLS pin, fCL could be selected via “Set display clock CL frequency” instruction, and frame frequency could be calculated using the following equation. fCL = (Duty ratio) × (Frame frequency) 26 • Product Specification (V1.0) 12.28.2005 EPL09060 9 COM/60 SEG LCD Driver 7.5 Reset Circuit When the /RES input comes to the “L” level, this LSI returns to its default state.

According to the status in static indicator mode, power save is entered through one of two modes (sleep and standby mode). Power Save mode is released by the “Display ON” & “Entire Display OFF” instructions.

The internal modes during sleep mode are as follows: The oscillator circuit and the LCD power supply circuit are stopped. All liquid crystal drive circuits are stopped, as well as the segment and common driver output VSS level. When a “static indicator on” instruction is issued in the sleep mode, the LSI goes into the standby mode. Standby Mode All operations of the dynamic LCD display section are stopped, only the static display circuits for the indicators operate and hence the current consumption will be the minimum necessary for static drive. The internal conditions in the standby state are as follows: The power supply circuit for LCD drive is stopped. The oscillator circuit will still be operating. The LCD drive circuits for dynamic display are stopped and the segment and common driver outputs will be at the VSS level. The static display section will still be operating. When a reset instruction is issued in the standby mode, the LSI goes into a sleep mode. 36 • Product Specification (V1.0) 12.28.2005 EPL09060 9 COM/60 SEG LCD Driver 9 Application Information 9.1 Instruction Procedure Examples 9.1.1 Initial Setup (From power application to display ON using internal power supply circuits) V D D -V S S P o w e r O N P o w e r S t a b iliz a t io n I n p u t R e s e t S ig n a l W a it f o r m o r e t h a n 2 0 m s I n it ia l s e t t in g s s t a t e ( d e f a u lt ) U s e r s e t t in g s v ia in s t r u c t io n in p u t ( 1 ) D U T Y s e le c t L C D b ia s s e le c t C L f r e q u e n c y s e le c t A D C s e le c t S H L s e le c t U s e r s e t tin g s v ia c o m m a n d in p u t ( 2 ) C o n t r a s t c o n t r o l v o lu m e U s e r s e t tin g s v ia c o m m a n d in p u t ( 3 ) P o w e r c o n tro l V C ,V R ,V F = (1 , 1 , 1 ) W a it in g f o r m o r e t h a n 3 0 0 m s t o s t a b iliz e t h e L C D p o w e r le v e ls E n d o f in it ia l s e t t in g s L C D d is p la y s c r e e n s e t tin g s D is p la y s t a r t lin e s e t W r it in g s c r e e n d a t a , e t c .
