Serial interface
When KS0711 active(CS1L High), serial data serial clock intput enabled, when KS0711 active, 8-bit shift register 3-bit counter which enable serial interface reset. Serial data read rising edge serial clock going into D6(SCLK) processed 8-bit parallel data every eight clock pulse.
Serial data input display data when High control data when Low. Since clock signal(SCLK) easy affected external noise caused line length, operation check actual machine recommended.

Busy Flag
busy flag indicates whether KS0711 operating not. When High Read Status operatio this device busy status will accept only Read Status instruction. cycle time correct, microprocessor needs check this flag before each instruction, which improves microprocessor performance.
Data transfer
KS0711 uses holder internal data data transfer with MPU. When writing data from RAM, data automatically transferred from holder display data shown Figure when reading data from display data MPU, data initial read cycle stored holder(dummy read) this stored data read onto from holder next data read cycle shown Figure This means that dummy read cycle must inserted between each pair address sets when sequence address sets executed, therefore, data specified address cannot output with Read Display Data instruction right after address sets, output second read data.

Each pixel selected when page column address specified. rows divided into pages lines ninth page with single line (DBO only). Data read from written lines each page directly through DB7. display data from microprocessor corresponds common lines.
microprocessor read from write through buffer. Since controller operates independently, data written into same time data being displayed without causing flicker.
Page Address Circuit
This ciruit providing page address Display Data shown Figure incorporates 4-bit Page Address register changed only Page instruction. Page address 8(D3 High, Low) special area icons display data only valid. When Page Address above impossible access DDRAM.
Line Address Circuit
This circuit assigns DDRAM line address corresponding first line(COMI) display. Therefore, setting line address repeatly, possible realize screen scrolling page switching without changing contents on-chip shown Figure incorporates 6-bit Line Address register changed only Initial Display Line instruction 6-bit counter circuit. beginning each frame, contents register copied line counter which increased signal generates line address transferring 264-bit data Control circuit.

Power Supply Circuit
This power supply circuit generating voltages dirve consists voltage converter, voltage regulator, voltage follower. valid only master operation. Voltage converter boosts logic voltage(VDD) times this boosted voltage(VOUT) delivered voltage regulator. Voltage regulator adjusts between VOUT this adjusted voltage sent voltage follower. Vlcd voltage(VO) resistively devided into four voltage levels(V1, V4), those output impedances converted voltage follower increasing drive capability.
Power supply circuit controlled Power Control instruction. There eight combination states according instruction sets(VB,VR,VF). Table shows useful combinations which recommended, remaining combination states impractical, recommended used.
