1.10.290. RESERVE_DATA1_AFTER_CONFIGURATION

Specifies how the Data[1]/ASDO pin should be used when the device is operating in user mode after configuration is complete. Depending on the current device and configuration scheme, this pin can be reserved as a regular I/O pin, as an input that is tri-stated, as an output that drives ground, as an output that drives an unspecified signal, or compiler configured. If the Data[1]/ASDO pin is reserved as a regular I/O pin, the Data[1]/ASDO pin can be used as an ordinary I/O pin after configuration. If the Data[1]/ASDO pin is only used to interface with external memory for configuration, the Data[1]/ASDO pin should be reserved as compiler configured.
