cases, the FPGA’s VCCO_1 and VCCO_2 supply voltages
must also be 3.3V to match the parallel Flash PROM. There
are some 1.8V parallel Flash PROMs available and the
FPGA interfaces with these devices if the VCCO_1 and
VCCO_2 supplies are also 1.8V.

Sequence
Like SPI Flash PROMs, parallel Flash PROMs typically
require some amount of internal initialization time when the
supply voltage reaches its minimum value.
