Function
Address Bus
These inputs interface with eight bits of the
system’s address bus to select one of the
internal registers for read or write.
Data Bus
Bidirectional tristate data lines which
interface with the system’s data bus. Their
configuration is controlled by the level of pin
DBW (Data Bus Width), output drivers are
controlled by WR/RW (Write enable or
Read/Write selection).
