SPI MODES DESCRIPTION
Multiple IS25CQ032 devices can be connected on the
SPI serial bus and controlled by a SPI Master, i.e.
microcontroller, as shown in Figure 1. The devices
support either of two SPI modes:

Note: 1. The Write Protect (WP#) and Hold (HOLD#) signals should be driven high or low as
appropriate.

The difference between these two modes is the clock
polarity when the SPI master is in Stand-by mode: the
serial clock remains at “0” (SCK = 0) for Mode 0 and
the clock remains at “1” (SCK = 1) for Mode 3. Please
refer to Figure 2. For both modes, the input data is
latched on the rising edge of Serial Clock (SCK), and
the output data is available from the falling edge of
SCK.
