How long should I wait after nSTATUS goes high before sampling the AVST_READY signal when configuring Intel® Stratix® 10 devices in Avalon-ST configuration mode?

Description

The AVST_READY signal doesn’t change to a valid value until after the nSTATUS pin goes high in Intel® Stratix® 10 devices, when configuring in Avalon-ST mode. It is recommended to wait at least 500 us after the  nSTATUS pin goes high before sampling AVST_READY and proceeding with the configuration process.
