In addition to hardware reset the microcontroller can also issue a SPI command to initiate software reset. Software reset is triggered by setting the RESET bit in the register CONFIG to logic 1, which re-initializes the device with all registers set to their default values. Once the re-initialization process is completed, the INT pin is asserted low, and the interrupt register bit POR and the SPI status flag POR are both asserted to notify the microcontroller that the device has completed the reset process.
