PRODUCTION DATA
The Octal Serial Peripheral Interface (OSPI™) module is a kind of Serial Peripheral Interface (SPI) module which allows single, dual, quad or octal read and write access to external flash devices.
The OSPI module is used to transfer data, either in a memory mapped direct mode (for example a processor wishing to execute code directly from external flash memory), or in an indirect mode where the module is set-up to silently perform some requested operation, signaling its completion via interrupts or status registers.
For more information, see Octal Serial Peripheral Interface (OSPI) section in Peripherals chapter in the device TRM.
