Oki Electric Industry ML9041
The ML9041 used in combination with an 8–bit or 4–bit microcontroller controls the operation of a character type dot matrix LCD. This pin should be open in the Serial I/F Mode. The input pin for data input/output between the CPU and the ML9041 and for activating instructions in the Parallel I/F Mode.GENERAL DESCRIPTION
