All values are typical unless otherwise specified.
All revisions of the ’5402 can be operated with an external clock source, provided that the proper voltage levels be driven on the X2/CLKIN pin.
It should be noted that the X2/CLKIN pin is referenced to the device 1.8V power supply (CVdd), rather than the 3V I/O supply (DVdd). Refer to
the recommended operating conditions section of this document for the allowable voltage levels of the X2/CLKIN pin.

#This value represents the current consumption of the CPU, on-chip memory, and on-chip peripherals. Conditions include: program execution
from on-chip RAM, with 50% usage of MAC and 50% usage of NOP instructions. Actual operating current varies with program being executed.
||This value was obtained using the following conditions: external memory writes at a rate of 20 million writes per second, CLKOFF=0, full-duplex
calculation is performed, refer to the Calculation of TMS320C54x Power Dissipation Application Report(literature number SPRA164).
