12.6 Power-Supply Sequence
When the internal voltage regulator is disabled by setting ENZ to VDD and both voltages are being supplied externally,
there are power sequencing requirements. During power up, the 1.8-V supply (PWTST) should not begin to ramp
up until after the 3.3-V supply (VDD3V, AVD[4:1], VDPLL) reaches at least 2.5 V (see Figure 127). During power
down, the 1.8-V supply should begin to ramp down before the 3.3-V supply (see Figure 128). The exact timing of
the power down is dependant upon the capacitance of the design. At no time during device operation should the 1.8-V
supply have a higher voltage than the 3.3-V supply.
