B.5.1. Overview

The quad SPI flash controller uses the register slave interface to select the operation modes and configure the data slave interface for data transfers. The quad SPI flash controller uses the data slave interface for direct and indirect accesses, and the register slave interface for software triggered instruction generator (STIG) operation and SPI legacy mode accesses.

Accesses to the data slave are forwarded to the direct or indirect access controller. If the access address is within the configured indirect address range, the access is sent to the indirect access controller.
