RESERVE_DATA1_AFTER_CONFIGURATION<br />

RESERVE_DATA1_AFTER_CONFIGURATION<br />

Type<br />

Specifies how the Data[1]/ASDO pin should be used when the device is operating in<br />

user mode after configuration is complete. Depending on the current device and<br />

configuration scheme, this pin can be reserved as a regular I/O pin, as an input that is<br />

tri-stated, as an output that drives ground, as an output that drives an unspecified<br />

signal, or compiler configured. If the Data[1]/ASDO pin is reserved as a regular I/O<br />

pin, the Data[1]/ASDO pin can be used as an ordinary I/O pin after configuration. If<br />

the Data[1]/ASDO pin is only used to interface with external memory for<br />

configuration, the Data[1]/ASDO pin should be reserved as compiler configured.<br />
