To use the DPI on the expansion II interface, disable any signal driving a
DPI pin with the associated switch. The pinout of the expansion connec-
tors can be found in
Flags and Memory Selects
The processor has four asynchronous memory selects, four flag pins, three
interrupt request pins, and one timer expired pin. All flag/memory pins
are multi-functional and depend on the ADSP-21479 processor setup.
Table 2-3
