Slave
MOSI = Master Out, Slave In
The Master is the ASIC/MCU and the Slave is the memory device.
The Master always clocks data out on the rising edge of SCK and always clocks data in on the falling edge of SCK.
The Slave always clocks data out on the falling edge of SCK and always clocks data in on the rising edge of SCK.

Stresses beyond those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device.
Functional operation of the device at these or any other
conditions beyond those indicated in the operational sec-
tions of this specification is not implied. Exposure to abso-
lute maximum rating conditions for extended periods may
affect device reliability. Voltage extremes referenced in the
“Absolute Maximum Ratings” are intended to accomodate
short duration undershoot/overshoot conditions and does
not imply or guarantee functional device operation at
these levels for any extended period of time.
