Abstract: Realized are a switch on/off control method and a switch circuit that can reduce a processing load when controlling on/off of a switch whose various operations are controlled based on control data. All commands in a command table included in a RAM are DMA-transferred to an SPI controller, and the DMA-transferred commands are transmitted to an IPD via SPI communication, so as to perform on/off control. DIAG commands irrelevant to the on/off control of the IPD are written in advance in the entire region of the command table, transfer source addresses from which the commands are DMA-transferred to the IPD at phases at which the IPD is to be controlled to be turned on and off are calculated, and an ON command and an OFF command for controlling the IPD to be turned on and off are written over the diagnosis commands that were written in advance at the calculated transfer source addresses.
