Signals of Type “I: Constant” must either be constantly driven by the host or have a pull-up or pull-down (in
case the host is likely to tri-state the signal during power down modes). The constant drive is used to
ensure defined operation of the part and to minimize leakage current during low power modes.
WP is used as write-protect for the internal module SPI Flash. For production use, this pin should be
pulled low. For end application, this pin can be controlled by the host microcontroller to enable in field
Flash updates.
