How can I use an 8-bit peripheral with the XTEND?

• In a 16-bit environment, 8-bit peripherals (UART's, D-to-A's, etc) may be connected to either the lower or upper 8-bits of the data bus.  Recall that the lower 8-bits are on even address boundaries (0x00000h, 0x00002h, etc) and the upper 8-bits are on odd address boundaries (0x00001, 0x00003, etc.).  The XTEND-G3 and XTEND-S3 connect all the 8-bit peripherals to the lower 8-bits of the data bus.
