1.10.299. RESERVE_NWS_NRS_NCS_CS_AFTER_CONFIGURATION

Specifies how the nWS, nRS, nCS, and CS 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, or as outputs that drive an unspecified signal. If this pin is reserved as a regular I/O pin, the nWS, nRS, nCS, and CS pins can be used as ordinary I/O pins after configuration.
