1.10.288. RESERVE_DATA0_AFTER_CONFIGURATION
Specifies how the Data[0] pin should be used when the device is operating in user mode after configuration is complete. Depending on the current device and configuration scheme, the Data[0] 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[0] pin is reserved as a regular I/O pin, the Data[0] pin can be used as an ordinary I/O pin after configuration. If the Data[0] pin is only used to interface with external memory for configuration, the Data[0] pin should be reserved as compiler configured.
