Description
CS All Chip Select A low level selects the device and a high level puts the device in standby mode. If CS is brought
high during a program cycle, the cycle will complete and then the device will enter standby mode.
When CS is high, SO is in high-Z. CS must be driven low after power-up prior to any sequence
being started.
SCK
All Serial Clock Synchronizes all activities between the memory and controller. All incoming addresses, data and
instructions are latched on the rising edge of SCK. Data out is updated after the falling edge of
SCK.
SI SPI Serial Data In Receives instructions, addresses and data on the rising edge of SCK.
SO SPI Serial Data Out Data is transferred out after the falling edge of SCK.
