The configuration interface is used to configure the OSPI module and perform software controlled flash accesses using the OSPI_FLASH_CMD_CTRL_REG register (for more information refer to Section 12.3.2.4.11, Software Triggered Instruction Generator (STIG)). Depending on the address it routes the incoming interconnect transfer to the Low level SPI protocol controller or to the ECC aggregator. The configuration port is also used to interact with the OSPI configuration and SRAM ECC registers.
The configuration interface supports only 32-bit accesses. For single byte or halfword manipulations software should perform read-modify-write operations.
