描述：
The MCCOG22005A6W-BNMLWI is a 20-character x 4 lines Alphanumeric LCD Display with negative transmissive polarizer and LED backlight (white). It features STN (blue) LCD panel. This system interface chip has all four kinds of interface type with MPU: 4-bit bus, 8-bit bus, serial and fast I2C interface. 4-bit bus or 8-bit bus is selected by DL bit in the instruction register. During read or write operation, two 8-bit registers are used. One is data register (DR), the other is instruction register(lR). The data register (DR) is used as temporary data storage place for being written into or read from DRAM/CGRAM/ICON RAM, target RAM is selected by RAM address setting instruction. Each internal operation, reading from or writing into RAM, is done automatically. Soto speak, after MPU reads DR data, the data in the next DDRAM/CGRAM/ICON RAM address is transferred into DR automatically. . 6 O"clock View direction . 1/16 Duty, 1/5 bias duty .
