•
Output of up to 23-bit address bus and control signals to be used with a non-muxed external bus
Bidirectional 16-bit external data bus with option to disable upper half
Visibility of internal bus activity
Single-chip modes
The external bus interface is not available in these modes.
Expanded modes
Address, data, and control signals are activated on the external bus in normal expanded mode and
special test mode.
Emulation modes
The external bus is activated to interface to an external tool for emulation of normal expanded mode
or normal single-chip mode applications.
