The device contains two flash subsystems where:
- FSS0 supports Octal-SPI flash with XIP
- See Flash Subsystem 0 (FSS0), OSPI Features, and OSPI Not Supported Features for list of all features
- FSS1 supports Octal flash or HyperRAM
- With Hyberbus for interconnect with HyperRAM
- Provides access to external flash devices via OSPI
- Review Flash Subsystem 1 (FSS1) for list of all features
The FSS implementation can support the following interfaces:
- Two OSPIs with:
- FSS0 as FSS0_OSPI0 (also known as OSPI0)
- FSS1 as FSS1_OSPI_0 (also known as OSPI1)
- One OSPI and one HyperRAM with
- FSS0 as OSPI0
- FSS1 as HyperRAM
- These Mode of Operations are also described in Table 12-220
