Type

HOLD

: The

pin is used to temporarily pause serial communication without

deselecting or resetting the device. While the

pin is asserted, transitions on the

SCK pin and data on the SI pin will be ignored, and the SO pin will be in a high-

impedance state.

The

pin must be asserted, and the SCK pin must be in the low state in order for a

Hold condition to start. A Hold condition pauses serial communication only and does not

have an effect on internally self-timed operations such as a program or erase cycle.

Please refer to “Hold” on page 45 for additional details on the Hold operation.

The

pin is internally pulled-high and may be left floating if the Hold function will not

be used. However, it is recommended that the

pin also be externally connected to

VCC whenever possible.

DEVICE POWER SUPPLY:

The VCC pin is used to supply the source voltage to the

device.

Operations at invalid VCC voltages may produce spurious results and should not be

attempted.

GND

GROUND:

The ground reference for the power supply. GND should be connected to the

system ground.
