Advisory

VREG: VREG Will be Enabled During Power Up Irrespective of VREGENZ

Revisions Affected

0, A, B

Details

During power up of the 3.3-V VDDIO, the internal Voltage Regulator (VREG) will be active until the 1.2-V VDD supply reaches approximately 0.7 V. After this time, the VREGENZ pin tied to VDDIO will disable the internal VREG. This will not impact device operation.

Workarounds

None
