FSPI Controller – XIP functionality (SINGLE, DUAL, QUAD and OCTAL SPI Bus Controller with Double Data Rate support)
Overview
The FSPI is a fully configurable SINGLE, DUAL, QUAD and OCTAL SPI master/slave device, which allows user to configure polarity and phase of serial clock signal (SCK). The FSPI system is flexible enough to interface directly with numerous standard product peripherals from several manufacturers. It supports two DMA modes: single transfer and multitransfer. These modes allow FSPI to interface to higher performance DMA units, which can interleave their transfers between CPU cycles or execute multiple byte transfers. FSPI is fully customizable, which means it is delivered in the exact configuration that meets users’ requirements.
