Abstract

PURPOSE:To obtain either mode by a program instruction by dividing a stand-by mode into the 1st stand-by mode and the 2nd stand-by mode wherein, specially, low power consumption is required. CONSTITUTION:When the 1st stand-by mode is indicated by the instruction, a central processing part 3 sends an instruction and a stand-by control circuit 8 sets a stand-by flag 1. The stand-by control circuit 8 sends a halt signal to respective processing part on the basis of the flag and the respective processing part is held in a halt state. Then, the stand-by control circuit 8 sends a clock stop signal to a frequency dividing circuit 2, whose frequency dividing function is stopped.
