PRODUCTION DATA
The DPHY440 is continuously monitoring the DPHY LP protocol for entry into the ULPS state. Upon entry into the ULPS state, the DPHY440 keeps active the logic necessary for LP signaling (LP rx, LPtx, LP state machine, so forth). All logic needed for HS operation are disabled. This allows for a lower power state than can be achieved when in operating other LP power states.
ULPS mode can only be entered from LP Mode.
