Switching Characteristics specify how the processor changes its signals. You have no control over this timing—circuitry external to the
processor must be designed for compatibility with these signal characteristics. Switching characteristics tell you what the processor
will do in a given circumstance. You can also use switching characteristics to ensure that any timing requirement of a device con-
nected to the processor (such as memory) is satisfied.
Timing Requirements apply to signals that are controlled by circuitry external to the processor, such as the data input for a read opera-
tion. Timing requirements guarantee that the processor operates correctly with other devices.

NOTES
1Applies after the power-up sequence is complete. At power-up, the processor’s internal phase-locked loop requires no more than 3000 CLKIN cycles while
RESET is
low, assuming stable VDD and CLKIN (not including start-up time of external clock oscillator).
2Only required if multiple ADSP-2106xs must come out of reset synchronous to CLKIN with program counters (PC) equal (i.e., for a SIMD system). Not required
for multiple ADSP-2106xs communicating over the shared bus (through the external port), because the bus arbitration logic synchronizes itself automatically after
reset.
