Read/Write R/W=high: Data of DB0~DB7 can be read by CPU. R/W=low: Data of DB0~DB7 can be written into LCD driver IC at the falling edge of E when CS1 and CS2 is high Enable: When write (R/W=low): Data of DB0~DB7 is latched at the fall of E. When read(R/W=high): Data is read while E is at high level.
