25.1 Overview

Non-volatile memory (NVM) is a reprogrammable flash memory that retains program and data storage, even when powered off. The NVM Controller (NVMCTRL) embeds two banks; one bank can be read while the other is programmed (RWW). It is connected to the AHB and APB bus interfaces for system access to the NVM block. The AHB interfaces are used for reads and writes to the NVM block, while the APB interface is used for commands and configuration.
