The Flash Subsystem (FSS) provides access to external flash devices via Octal SPI (OSPI) andHyperBus™ interface.
The FSS includes two OSPIs and one HyperBus interface. For more information, see Octal Serial Peripheral Interface (OSPI) and Section 12.3.3, HyperBus Interface.
Table 12-284 shows FSS allocation across device domains.
| Instance | Domain | ||
| WKUP | MCU | MAIN | |
| MCU_FSS0 | - | ✓ | - |
Figure 12-217 shows the FSS overview.
The first FSS path (FSS0) has access to either OSPI0 or HyperBus interface. The second FSS path (FSS1) has access only to OSPI1 and can be configured with or without ECC.
