Updated footnote of
as
“Note that the clock needs to be constrained
to ~26.67MHz for reliable operation at high operating temperatures. The throughput
of the SPI Flash block is therefore restricted to ~13 MBps for Quad mode and ~3
MBps for single mode”.
Added “ The clock for the SPI Flash block needs to be constrained to ~26.67MHz for
reliable operation at high operating temperatures.
