ID[1:0] (Identification). The device whose ID input balls matches the value of bits ID[0:1] responds
to read and write cycles to register space.

MAX_ID (Maximum Device ID). This field controls the RAM address mapping when multiple
devices are used in a cascaded configuration, using the ID[1:0] inputs. It should be programmed to
the highest ID value that is found by software in order to map all available boot blocks into usable
address space.
IF_CFG (Interface Configuration). Reflects the state of the IF_CFG input pin.
In a cascaded configuration, this register controls which device provides the register space. The
value of bits ID[0:1] is compared to the value of the ID configuration input balls, as defined in
Section 9.6. The device whose ID input balls matches the value of bits ID[0:1] responds to read
and write cycles to register space.
