10 9.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 IR write as an internal operation (display clear, etc.) 1 Read busy flag (DB7) and address counter (DB to DB7) 1 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= and R/W=1, the busy flag is output to DB7. The next instruction must be written after ensuring that the busy flag is. 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 8 8 bits or 8 characters. Below figure is the relationships 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 Page 1 of 27

11 Display position DD address Line by 8-Character Display Character Generator ROM (ROM) The ROM generate 5 8 dot or 5 1 dot character patterns from 8-bit character codes. See Table 2. Character Generator () In, the user can rewrite character by program. written, and for 5 1 dots, four character patterns can be written. For 5 8 dots, eight character patterns can be Write into DD the character code at the addresses shown as the left column of table 1. To show the character patterns stored in. Page 11 of 27
