1) Bit-addressable special function registers
2) This special function register is listed repeatedly since some bits of it also belong to other functional blocks.
3) “X“ means that the value is undefined and the location is reserved
4) This SFR is a mapped SFR. For accessing this SFR, bit PDIR in SFR IP1 must be set.
