title: NXP SPI Flash Interface (SPIFI)

description:
  NXP SPIFI is a specialized SPI interface for serial Flash devices.
  It supports one Flash device with 1-, 2- and 4-bits width in SPI
  mode 0 or 3. The controller operates in either command or memory
  mode. In memory mode the Flash is accessible from the CPU as
  normal memory.
