1 Applies after the power-up sequence is complete. At power-up, the processor’s internal phase-locked loop requires no more than 100 μs while RESET is low, assuming stable
VDD and CLKIN (not including startup time of external clock oscillator).
2 Only required if multiple ADSP-21061s must come out of reset synchronous to CLKIN with program counters (PC) equal. Not required for multiple ADSP-21061s commu-
nicating over the shared bus (through the external port), because the bus arbitration logic automatically synchronizes itself after reset.
