773 * Description: Test the address bus wiring in a

780 * address and size of the region are

783 * Notes: For best results, the selected base
784 * address should have enough LSB 0's to
785 * guarantee single address bit changes.
786 * For example, to test a 64-Kbyte
787 * region, select a base address on a
788 * 64-Kbyte boundary. Also, select the
789 * region size as a power-of-two if at
