A.1.4. Booting and Configuration Device Response to External Configuration and Reset Events

The following table summarizes the device response to various external configuration and reset events.

Note: The HPS_COLD_RESET pin serves both as an input to reset the HPS and as an output to the external system to indicate that the HPS is in reset. Do not connect HPS_COLD_nRESET to the external flash. The SDM controls the reset of the external flash separately.
