This rail is connected to ground; it only needs a voltage if eFuses are to be programmed. FUSE_VDD should be supplied by
following the power up sequence given in
1. Measure worst case power consumption on individual rails using directed test on i.MX35.
2. Correlate worst case power consumption power measurements with worst case power
3. Combine common voltage rails based on power supply sequencing requirements
4. Guard band worst case numbers for temperature and process variation. Guard band is based on
5. The sum of individual rails is greater than real world power consumption, as a real system does
