(1) Assumes the following conditions: 25 C case temperature; 60% CPU utilization; EMIF at 50% utilization (100 MHz), 50% writes, (32 bits
for GDH, 16 bits for RFP), 50% bit switching; two 10-MHz SPI at 100% utilization, 50% bit switching.
The actual current draw is highly application-dependent. For more details on core and I/O activity, refer to the TMS320C672x Power
Consumption Summary Application Report (literature number SPRAAA4).
