1. Reset value reflects the Pre-Life Cycle of the device.
2. Reset value is the Life Cycle of the device.
Field
Life Cycle - as determined by the SSCM by reading the LC slots. The encoding is:
JDP_PROD = 110
CUST_DELIV = 011

Functional description

The primary purpose of the SSCM is to provide information about the current state and
configuration of the system that may be useful for configuring application software and for
debug of the system.
53.4.1 DCF mechanism
The DCF mechanism has been developed to handle settings of device parameters via OTP
flash memory.
Starting at location UTEST_OFFSET the user can store a series of DCF records - the
device will process these records during the system reset sequence before the CPU leaves
reset. The first record needs to be a start record followed by an application-specific number
of data records as required, and finally a stop record.
Each record is 64 bits in length.
must be placed at UTEST_OFFSET to indicate to the device that the following data records
should be processed.
