STATUS REGISTER
brought low while SCK is low. The SO pin is in a high
impedance state during the time the part is paused, and
transitions on the SI pins will be ignored. To resume
communication,
HOLD is brought high, while SCK is low.
(
HOLD should be held high any time this function is not
being used.)
HOLD may be tied high directly to VCC or
tied to VCC through a resistor. Figure 9 illustrates hold
timing sequence.

STATUS REGISTER
The status register defines the protection status of the
device. The register features three protection bits which
allow the user to protect the desirable part of the memory
array. There are seven different variations for the protec-
tion mechanism. The protection can vary from one page
to as much as half of the entire array. These areas and
associated address ranges are protected by configuring
the protection bits of the status register through WRSR
instruction. Once the three protection bits are set, the
associated memory can be read but not written until the
protection bits are reset.
