27.5.1 Principle of Operation

The NVM Controller is a Client on the AHB (AHB0, AHB1 and AHB2) and APB buses. It responds to commands, read requests, and write requests based on user configuration. AHB0 and AHB1 allow access to the NVM main address space, the auxiliary space, and the page buffer. AHB2 provides access to the SmartEEPROM interface that indirectly accesses the reserved area in the NVM for EEPROM emulation.
