1.10.293. RESERVE_DATA7_THROUGH_DATA2_AFTER_CONFIGURATION

Specifies how the Data[7..2] pins should be used when the device is operating in user mode after configuration is complete. Depending on the current device and configuration scheme, these pins can be reserved as regular I/O pins, as inputs that are tri-stated, as outputs that drive ground, as outputs that drive an unspecified signal, or compiler configured. If the Data[7..2] pins are reserved as a regular I/O pins, the Data[7..2] pins can be used as ordinary I/O pins after configuration. If Data[7..2] pins are only used to interface with external memory for configuration, the Data[7..2] pins should be reserved as compiler configured.
