RESERVE_RDYNBUSY_AFTER_CONFIGURATION
Specifies how the RDYnBUSY 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 RDYnBUSY
pin can be reserved as a regular I/O pin, as an input that is tri-stated, as an output that drives ground, or
as an output that drives an unspecified signal. If this pin is reserved as a regular I/O pin, the RDYnBUSY
pin can be used as an ordinary I/O pin after configuration.
