Register descriptions

The following registers are available in the PASS. The shaded bits are reserved for future
use. For future compatibility, only write '0' to these bits; they always read '0'.
68.2.1.1 Life Cycle Status register (LCSTAT)
The Life Cycle Status Register reflects the production status and censorship status of the
device. It is possible to mature the device (move the device life cycle forward), but never to
revert the life cycle to an earlier state.
The reset value of the LCSTAT register LIFE field derives from an external life cycle
management module (like SSCM). It is a 3-bit life cycle. This register simply displays the life
cycle input from external blocks.
