Transfers data serially out of the device on the falling edge of SCK.
Transfers data serially into the device. Device latches commands, addresses, and
program data on SI on the rising edge of SCK.
Provides serial interface timing. Latches commands, addresses, and data on SI on rising
edge of SCK. Triggers output on SO after the falling edge of SCK.
Places device in active power mode when driven low. Deselects device and places SO
at high impedance when high. After power-up, device requires a falling edge on CS#
before any command is written. Device is in standby mode when a program, erase, or
Write Status Register operation is not in progress.
Pauses any serial communication with the device without deselecting it. When driven
low, SO is at high impedance, and all input at SI and SCK are ignored. Requires that
CS# also be driven low.
Protects the memory area specified by Status Register bits BP2:BP0. When driven low,
prevents any program or erase command from altering the data in the protected
memory area.
