R61509V

Target Spec

80-System 8-bit Bus Interface

When transferring 16-bit instruction, it is divided into upper and lower 8 bits, and the upper 8 bits are transferred first. The RAM write data is also divided into upper and lower 8 bits, and the upper 8 bits are transferred first. The RAM write data is expanded into 18 bits internally as shown below. The unused DB pins must be fixed at either IOVCC1 or GND level. When transferring the index register setting, make sure to write upper byte (8 bits).
