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.
