BIT
consisting of the SBC type and SBC version. Bit 11 of GP0 will reflect a logic 0 indicating the content of this register
to be the ‘Device Identification Code’ after Power-on of the SBC. Once written to this register, bit 11 will be set to a
permanent logic 1 indicating that the device code has been overwritten with application-specific information. Bit 11
cannot be reset any more with software control. Bit 11 will be cleared again with the next Power-on condition at
pin BAT42 with reloading the device code into GP0.
