Transfers parallel data into the device on the rising edge of SCK or 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.
When driven low, prevents any program or erase command from altering
the data in the protected memory area specified by Status Register bits
(BP bits). If the system asserts V
programming operation is provided.

Ground
Transfers data serially out of the device on the falling edge of SCK.
