Signature Row Description
6.9.2.1
Device ID n
Each device has a Device ID, identifying the device and its properties, such as memory sizes, pin count,
and die revision. This can be used to identify a device and hence, the available features by software. The
Device ID consists of three bytes: SIGROW.DEVICEID[2:0].
