To realize efficient control
processing.SOLUTION: In a
game machine, a CPU is capable of executing: third
processing which performs first
processing of writing, by the CPU, 55H into a 1-
byte first general-purpose register and then writing, by the CPU, a first general-purpose register value into a 1-
byte first RAM, and performs second processing of writing, by the CPU, AAH into the 1-
byte first general-purpose register and then writing, by the CPU, the first general-purpose register value into a 1-byte second RAM; and sixth processing which performs, after the third processing, fourth processing of writing, by the CPU, a first RAM value into the first general-purpose register and then comparing, by the CPU, the first general-purpose register value with 55H to determine whether or not they correspond to each other, and performs fifth processing of writing, by the CPU, a second RAM value to the first general-purpose register and then comparing, by the CPU, the first general-purpose register value with AAH to determine whether or not they correspond to each other.SELECTED DRAWING: Figure 130
