793 * Description: Test the address bus wiring in a

803 * Notes: For best results, the selected base
804 * address should have enough LSB 0's to
805 * guarantee single address bit changes.
806 * For example, to test a 64-Kbyte
807 * region, select a base address on a
808 * 64-Kbyte boundary. Also, select the
809 * region size as a power-of-two if at
