E xample:
In an ADSP-2111 application where external data memory is
used and no other outputs are active, power dissipation is
calculated as follows:
Assumptions:
External data memory is accessed every cycle with 50% of the
address pins switching.
External data memory writes occur every other cycle with
50% of the data pins switching.
Each address and data pin has a 10 pF total load at the pin.
