RESERVE_DCLK_AFTER_CONFIGURATION
Specifies how the DCLK 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 DCLK pin can be reserved as
a regular I/O pin, as a dedicated programming pin, or compiler configured. If this pin is reserved as a
regular I/O pin, the DCLK pin can be used as an ordinary output pin after configuration. If the DCLK pin
is only used to interface with external memory for configuration, the DCLK pin should be reserved as
compiler configured.
