Software reset causes a restart from the beginning of the compass firmware. It is intended primarily for development
purposes. As soon as the compass determines that it has received the RSET command, it initiates a reset of the
microcontroller. There can be no direct acknowledgment to this command, since all resources are re-initialized. Instead,
the host should recognize the receipt of the DPOWER message, which is sent as a normal part of the power-up
sequence, as an indication that the compass has reset. Because of the full reset, all power-up defaults will be restored.
