6.1.5 Flash

The F28044 contains 64K x 16 of embedded flash memory, segregated into four 16K x 16 sectors. Both devices also contain a single 1K x 16 of OTP memory at address range 0x3D 7800 – 0x3D 7BFF. The user can individually erase, program, and validate a flash sector while leaving other sectors untouched. However, it is not possible to use one sector of the flash or the OTP to execute flash algorithms that erase/program other sectors. Special memory pipelining is provided to enable the flash module to achieve higher performance. The flash/OTP is mapped to both program and data space; therefore, it can be used to execute code or store data information. Note that addresses 0x3F7FF0 – 0x3F7FF5 are reserved for data variables and should not contain program code.

NOTE

The F28044 Flash and OTP wait-states can be configured by the application. This allows applications running at slower frequencies to configure the flash to use fewer wait-states.

Flash effective performance can be improved by enabling the flash pipeline mode in the Flash options register. With this mode enabled, effective performance of linear code execution will be much faster than the raw performance indicated by the wait-state configuration alone. The exact performance gain when using the Flash pipeline mode is application-dependent.

For more information on the Flash options, Flash wait-state, and OTP wait-state registers, see the TMS320x280x, 2801x, 2804x DSP System Control and Interrupts Reference Guide.
