Implementation
Refer to the AMD Power Design Manager (PDM) for the most recent guidance on power-supply sequencing and management, including VCC_FUSE. When supplied, VCC_FUSE must power up AFTER the PMC/LPD domain supplies. If eFUSE is not intended to be used, connect VCC_FUSE to GND to avoid accidental programming of the eFUSE OTP registers.
If programming flexibility is required, a load switch is recommended to connect/disconnect the VCC_FUSE rail from its voltage regulator as needed.
