Pin Labels

SCK	Serial Clock	All commands, addresses, and input data are latched on the rising edge of the clock input, whereas output data is shifted out on the falling edge of the clock input.
SI	Serial Data	Serial Input for commands, addresses, or data. Inputs are latched on the rising edge of the serial clock.
SO	Serial Data	Serial Output for data. Data is shifted out on the falling edge of the serial clock.
CE#	Chip Enable	Chip Enable is a high to low transition on CE#. CE# must remain low for the duration of command sequences.
WP#	Write Protect	The Write Protect enables/disables BPL bit in the status register.
HOLD#	Hold	Temporarily stops serial communication with SPI flash memory without resetting the device.
