Abstract
A microcontroller is disposed on a receiving part of a wireless system in order to process a demodulation signal generated by a receiver circuit, and includes a memory and a CPU. The memory stores a control program of the microcontroller. The control program thereof includes a dual loop routine for an operation in reception standby mode. The dual loop routine has a first loop and a second loop included in the first loop. The CPU has an instruction set consisting of a plurality of instructions, and executes the instructions according to the program stored in the memory. The CPU executes an instruction irrelevant to an operation when the microcontroller is in reception mode during the second loop a number of times. The number of times is at least such that noise caused by the repetition of the second loop is lowered below a desired level.
