Address Bus, Bits 0-20. Core external address
bus. Affected or used by any transaction on the
internal core bus, including DMA transactions and
accesses to the internal memory.
Data Bus, Bits 15-0. Core external data bus. Used
for core access to external memory or I/O devices.
When accessing an 8-bit external memory or I/O
device, only D7-0 should be used.
