Description
Default Value (Bin)
This register holds the status of the reference sources supplied to the other device in
a master/slave configuration. It is a copy of the other device's sts_sources_valid
register. The register is part of the protection mechanism.

This register is used to force the device into a desired operating state, represented by
the binary values shown in Figure 10. Value 0 (hex) allows the control state machine
to operate automatically.
Bits (7:3) Unused.
Bits (2:0) Desired operating state (as per Figure 10).
This register is used to force the device to select a particular input reference source,
irrespective of its priority. Writing to this register temporarily raises the selected input
to priority “1”. Provided no other input is already programmed with priority “1”, and
revertive mode is on, this source will be selected.
