Bit-addressable special function registers
This special function register is listed repeatedly since some bits of it also belong to other functional blocks.
X means that the value is indeterminate or the location is reserved
Register is mapped by bit PDIR.
Register is mapped by bit RMAP.
“E” means that the value of the bit is defined by the logic level at pin PRGEN at the rising edge of the RESET
or HWPD signals
