NOTES
1
Applies after the power-up sequence is complete. At power-up, the processor’s internal phase-locked loop requires no more than 2000 CLKIN cycles while
RESET
is
low, assuming stable V
and CLKIN (not including start-up time of external clock oscillator).
2
Only 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 automatically synchronizes itself after
reset.
