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 indeterminate and the location is reserved.}
4) _{These registers are available in the CA step and later steps.}
