PROGRAMMING AND CONTROL
CONTROL REGISTER OVERVIEW
There are many programmable features that are controlled by
writing commands to the appropriate control registers using the
SPI. The following sections describe these controls and specify
each function, along with the corresponding register configuration.
The features available for configuration in this register space are:

CONTROL REGISTER STRUCTURE
The ADIS16350/ADIS16355 use a temporary, RAM-based
memory structure to facilitate the control registers listed
in Table 9. The operational configuration is stored in a flash
memory structure that automatically loads into the control
registers during the start-up sequence. Each nonvolatile register
has a corresponding flash memory location for storing the latest
configuration contents. The contents of each nonvolatile regis-
ter must be stored to flash manually.
Note that the contents of these registers are nonvolatile after they
are stored to flash. The flash update command, available in the
COMMAND register, provides this function. The ENDURANCE
register provides a counter that allows for reliability manage-
ment against the flash memory write cycle specification.
