Figure 47-2. VVDDCORE and VVDDIO Constraints at Startup
Switch-off the VDDIOMx and VDDIOPx power supply prior to or at the same time as VDDCORE.
No power-up or power-down restrictions apply to other power supplies.
• VDDIOP0 must be ≥ to V
• VDDIOM0 and VDDIOPM1 must reach V
(Tres + T1) after VDDCORE reached
within (Tres +T1 +T2) after VDDCORE has reached
