88 1. Self-Diagnostic Function by LED Blink. • Basic operation : At JR6, MPU is included in DSP, MPU accesses each peripheral (inside, exterior) device, and discover a defect by the ability of a read/write of data to be performed correctly. Since MPU operates by the program with a built-in Flash-ROM, when abnormalities are in MPU, Flash-ROM, and [...]
