1) X means that the value is indeterminate or the location is reserved.
2) SFRs with a comment in this column are mapped registers.
3) “E” means that the value of the bit is defined by the logic level at pin PRGEN at the rising edge of the RESET
Shaded registers are bit-addressable special function registers.
