Expanded modes
Address, data, and control signals are activated in normal expanded and special test modes when
accessing the external bus. Access to internal resources will not cause activity on the external bus.
Emulation modes
External bus is active to emulate, via an external tool, the normal expanded or the normal single
chip mode.}
