DisplayPort RX IP returns AUX_ACK instead of AUX_NACK when writing to an unsupported DPCD address

Description: The DisplayPort IP generates an illegal response to an AUX request when accessing a reserved DPCD address. The DisplayPort RX IP should return AUX_NACK when writing to an unsupported DPCD address, but the design responds with AUX_ACK.


Resolution: This should not impact typical usage or AUX transactions. It will be fixed in the next DisplayPort IP release.
