In special modes, this bit enables the bootloader ROM
In normal modes this bit is clear and cannot be written.
This bit reflects the inverse of the MODB input pin at the rising edge
of RESET. If MODB is low during reset, SMOD is set; if MODB is high
during reset, SMOD is cleared. Software can clear the SMOD bit, but
cannot set it. Thus, it is possible for software to change the operating
