Register addressing

Register File registers, including Group F paged registers (but excluding Group D), may be

addressed explicitly by means of a decimal, hexadecimal or binary address; thus R231,

RE7h and R11100111b represent the same register (see Figure 21). Group D registers can

only be addressed in Working Register mode.

An upper case “R” is used to denote this direct addressing mode.
