21 12-3 ST7066U controller data Function description The LCD display Module is built in a LSI controller, the controller has two 8-bit registers, an instruction register (IR) and a data register (DR). The IR stores instruction codes, such as display clear and cursor shift, and address information for display data (DD) and character generator (). The IR can only be written from the MPU. The DR temporarily stores data to be written or read from DD or. When address information is written into the IR, then data is stored into the DR from DD or. By the register selector (RS) signal, these two registers can be selected. RS R/W Operation 0 0 IR write as an internal operation (display clear, etc.) 0 1 Read busy flag (DB7) and address counter (DB0 to DB7) 1 0 Write data to DD or (DR to DD or ) 1 1 Read data from DD or (DD or to DR) Busy Flag (BF) When the busy flag is 1, the controller LSI is in the internal operation mode, and the next instruction will not be accepted. When RS=0 and R/W=1, the busy flag is output to DB7. The next instruction must be written after ensuring that the busy flag is 0. Address Counter (AC) The address counter (AC) assigns addresses to both DD and Display Data (DD) This DD is used to store the display data represented in 8-bit character codes. Its extended capacity is 808 bits or 80 characters. Below figure is the relationship between DD addresses and positions on the liquid crystal display. High bits Low bits Example:DD addresses 4E AC (hexadecimal) AC6 AC5 AC4 AC3 AC2 AC1 AC BC1602B~3n$ series

22 DD Address Display position DD address A 0B 0C 0D 0E 0F A 4B 4C 4D 4E 4F Example: 2-Line by 16-Character Display Character Generator ROM (ROM) The ROM generate 58 dot or 510 dot character patterns from 8-bit character codes. See Table 2. Character Generator () In, the user can rewrite character by program. For 58 dots, eight character patterns can be written, and for 510 dots, four character patterns can be written. Write into DD the character code at the addresses shown as the left column of table 1. To show the character patterns stored in BC1602B~3n$ series
