SPRS370C–SEPTEMBER 2006–REVISED OCTOBER 2007
A hardware reset (RESET) is required to place the DSP into a known good state out of power-up. The
RESET signal can be asserted (pulled low) prior to ramping the core and I/O voltages or after the core
and I/O voltages have reached their proper operating conditions. As a best practice, RESET should be
held low during power-up. Prior to deasserting RESET (low-to-high transition), the core and I/O voltages
should be at their proper operating conditions.
