Address modes R or IR can be used to specify a 4-bit Working Register. In
this format, the destination Working Register operand is specified by add-
ing 1110b (Eh) to the high nibble of the operand. For example, if Working
Register R12 (CH) is the destination operand, then ECh will be used as the
destination operand in the Op Code.
