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 RMAP in SFR SYSCON must be set.
5) The content of this SFR varies with the actual step of the C505 (eg. 01
