762 * Description: Test the address bus wiring in a

772 * Notes: For best results, the selected base
773 * address should have enough LSB 0's to
774 * guarantee single address bit changes.
775 * For example, to test a 64-Kbyte
776 * region, select a base address on a
777 * 64-Kbyte boundary. Also, select the
778 * region size as a power-of-two if at
