When this bit is set to 1, and both FBOOTSL and FPROGEN are set to 1. It
will enforce microcontroller reset to initial condition just like power on reset.
This action will re-boot the microcontroller and start to normal operation. To
read this bit in logic-1 can determine that the F04KBOOT mode is running.
