K1Y10 represents a device composed of 4 bits, K2Y10 represents a device composed of 8
bits, K3Y10 represents a device composed of 12 bit, and K4Y10 represents a device
composed of 16 bits. K1M100 represents a device composed of 4 bits, K2M100 represents
a device composed of 8 bits, K3M100 represents a device composed of 12 bit, and
