4.5.1 VREGENZ

Only the F29H85x 100-pin package supports the VREG mode where power is internally generated from the single-rail supply rail. For other package types, the dual-rail supply is required to power up the device.

Note: In general, the Internal and External VREG power sequencing detailed in the device-specific data sheet needs to be followed to start up the device properly.
