LCM时序分析 　　　　 　　　　 2011年06月 When– RCM=’0’ (MCU I/F), D[17:0] are used to MCU parallel interface data bus,and D0 is also the serial input/ output signal in SPI interface mode.In serial interface, D[17:1] are not used and should be connected to ground. I/O D[17:1]D[0]/SDIO Write enable in parallel interface.WRX: for 8080 MCUR/WX: for 6800 MCUD/CX: for 4-wire SPIIf not used, please connect this pin to VDDI or GND. I WRX(R/Wx)(D/CX) Read enable in 8080-parallel interface and Read/ Write operation enable pin in6800-parallel interface.In 8080-parallel interface, if not used, please connect this pin to VDDI.In 6800-parallel interface, if not used, please connect this pin to VDDI or GND. I RDX(E) Display data / Command selection pin in parallel and SCL in 3-pin SPI interface.D/CX=’1’: Display data.D/CX=’0’: Command data.If not used, please connect this pin to GND. I D/CX(SCL) Chip select input pin (“Low” enable).This pin can be permanently fixed “Low” in MCU interface mode only. I CSX Chip reset pin (“Low Active”).This signal low will reset the device and must be applied to properly initialize the chip. I RESX SPI interface selection pinSPI4W=’0’: 3-wire SPI. (default)SPI4W=’1’: 4-wire SPI.This pin is internal pull low. I SPI4W 8080/6800 MCU Interface mode selection.P68=’1’: select 6800-MCU parallel interfaceP68=’0’: select 8080-MCU parallel interfaceIf not used, please fix this pin at GND level.
