RESERVE_OTHER_AP_PINS_AFTER_CONFIGURATION
Specifies how the Data[15..8], PADD[23..0], NRESET, NAVD, NOE and NWE 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 these
pins are reserved as regular I/O pins, they can be used as ordinary I/O pins after configuration. If these
pins are only used to interface with external memory for configuration, these pins should be reserved as
compiler configured.
