M25P32
SPI MODES
These devices can be driven by a microcontroller
with its SPI peripheral running in either of the two
following modes:
–
CPOL=0, CPHA=0
–
CPOL=1, CPHA=1
For these two modes, input data is latched in on
the rising edge of Serial Clock (C), and output data
is available from the falling edge of Serial Clock
(C).
The difference between the two modes, as shown
in Figure 6., is the clock polarity when the bus
master is in Stand-by mode and not transferring
data:
–
C remains at 0 for (CPOL=0, CPHA=0)
–
C remains at 1 for (CPOL=1, CPHA=1)

Note: The Write Protect (W) and Hold (HOLD) signals should be driven, High or Low as appropriate.
