Functions
SCK
Serial Clock
To provide the timing of the serial interface.
Commands, addresses, or input data are latched on the rising edge of the clock input,
while output data is shifted out on the falling edge of the clock input.
Commands, addresses, or input data are latched on the rising edge of the clock input,
while output data is shifted out on the falling edge of the clock input.
SI
Serial Data Input
To transfer commands, addresses, or data serially into the device.
Inputs are latched on the rising edge of the serial clock.
Inputs are latched on the rising edge of the serial clock.
SO
Serial Data Output
To transfer data serially out of the device.
Data is shifted out on the falling edge of the serial clock.
Outputs Flash busy status during AAI Programming when reconfigured as RY/BY# pin.
See “Hardware End-of-Write Detection” on page 12 for details.

CE#
Chip Enable
The device is enabled by a high to low transition on CE#. CE# must remain low for the
duration of any command sequence.
duration of any command sequence.
WP#
Write Protect
The Write Protect (WP#) pin is used to enable/disable BPL bit in the status register.
HOLD#
Hold
To temporarily stop serial communication with SPI flash memory without resetting the
device.
