Figure 7-5 shows the sequence for three continuous
reads. The reads do not need to be to the same
memory address.
7.6.2
CONTINUOUS READS
Continuous reads allows the devices memory to be
read quickly. Continuous reads are possible to all
memory locations. If a non-volatile memory write cycle
is occurring, then Read commands may only access
the volatile memory locations.

driven low until the CS pin is driven inactive (VIH).
