1: The values of current consumption while the CPU is operating were measured when a test program that
consists of 55% load instructions, 23% arithmetic operation instructions, 1% mac instruction, 12% branch
instructions and 9% ext instruction is being executed in the built-in ROM continuously.
2: The LCD controller is included.
