Function
Microprocessor Data Bus
This bidirectional three-state bus provides
the general-purpose data path between the
IWE8 and an external master. The bus uses
little endian word order. MPDAT15 is the
MSB.
Microprocessor Address Bus
Provides the address of the current bus
cycle. Addresses are 16-bit aligned.
MPADR17 is the MSB of the bus
Microprocessor Chip Select
This signal is driven by the bus master to
indicate a read or write access.
