The board design must guarantee that supplies reach
90% level before transition to the next state, using Power
Management IC or other means.
The NVCC1 supply must not precede IOQVDD by more
than 0.2 V until IOQVDD has reached 1.5 V. If IOQVDD
is powered up first, there are no restrictions.
Raising NVCC2, NVCC21, and NVCC22 at the same
time as IOQVDD does not produce the slight increase in
current drain on IOQVDD (as described in
Note 5).
FUSE_VDD should not be driven on power-up for Silicon
Revision 2.0.1. This supply is dedicated for fuse burning
(programming), and should not be driven upon boot-up.

The NVCC1 supply must not precede IOQVDD by more
than 0.2 V until IOQVDD has reached 1.5 V. If IOQVDD
is powered up first, there are no restrictions.
The parallel paths in the flow indicate that supply group
NVCC2, NVCC21, and NVCC22, and supply group
FVCC, MVCC, SVCC, and UVCC ramp-ups are
independent.
FUSE_VDD should not be driven on power-up for Silicon
Revision 2.0.1. This supply is dedicated for fuse burning
(programming), and should not be driven upon boot-up.
Raising IOQVDD before NVCC21 produces a slight
increase in current drain on IOQVDD of approximately
3–5 mA. The current increase will not damage the IC.
