6. Spansion SPI Modes
February 27, 2009 S25FL064A_00_C4
A microcontroller can use either of its two SPI modes to control Spansion SPI Flash memory devices:
Input data is latched in on the rising edge of SCK, and output data is available from the falling edge of SCK for
both modes.
When the bus master is in standby mode, SCK is as shown in
Note
The Write Protect (W#) and Hold (HOLD#) signals should be driven high (logic level 1) or low (logic level 0) as appropriate.
Mode 0
Mode 3
CPOL = 0, CPHA = 0 (Mode 0)
CPOL = 1, CPHA = 1 (Mode 3)
SCK remains at 0 for (CPOL = 0, CPHA = 0 Mode 0)
SCK remains at 1 for (CPOL = 1, CPHA = 1 Mode 3)
