774 * Description: Test the address bus wiring in a

782 * selected by the caller.
784 * Notes: For best results, the selected base
785 * address should have enough LSB 0's to
786 * guarantee single address bit changes.
787 * For example, to test a 64-Kbyte
788 * region, select a base address on a
789 * 64-Kbyte boundary. Also, select the
