Serial Data Output: Transfers data serially out of the device on the falling edge of SCK.
Functions as an I/O pin in Dual and Quad I/O, and Quad Page Program modes.
Serial Data Input: Transfers data serially into the device. Device latches commands,
addresses, and program data on SI on the rising edge of SCK. Functions as an I/O pin in Dual
and Quad I/O mode.
Serial Clock: 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.
Chip Select: 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.
Hold: 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. Functions as an I/O pin in Quad I/O mode.
Write Protect: 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. Functions as an I/O pin in Quad I/O mode.
