1. An apparatus, comprising:
- a storage register to store first and second data values;
first, second, third and fourth data terminals to provide hexadecimal data from the data terminals in accordance with the first and second data values decoded to select four active terminals and the first, second and third terminals to provide octal data in accordance with the first and second data values decoded to select three active terminals;
a terminal to provide a clock signal, wherein the hexadecimal data is changed with the clock signal; and
a terminal to provide a strobe signal, wherein an identity of a register to output data is provided at the appropriate data terminals during the strobe signal.
