Notes: 1. These registers are bit-addressable.
Sixteen addresses in the SFR space are both byte-addressable and bit-addressable. The bit-addressable SFRs are those
whose address ends in 0 and 8. The bit addresses, in this area, are 0x80 through to 0xFF.
2. AUXR1 bit ENBOOT is initialized with the content of the BLJB bit inverted.
