To provide the timing for serial input and
output operations
To transfer commands, addresses or data
serially into the device.
Data is latched on the rising edge of SCK.
To transfer data serially out of the device.
Data is shifted out on the falling edge of
SCK.
To activate the device when CE is low.
The Write Protect ( WP ) pin is used to
enable/disable BPL bit in the status
register.
To temporality stop serial communication
with SPI flash memory without resetting
the device.
To provide power.
