The F28069, F28068, F28067, and F28066 devices contain 128K x 16 of embedded flash memory,segregated into eight 16K x 16 sectors. The F28065, F28064, F28063, and F28062 devices contain 64K x16 of embedded flash memory, segregated into eight 8K x 16 sectors. All devices also contain a single1K x 16 of OTP memory at address range 0x3D 7800 – 0x3D 7BF9. The user can individually erase,program, and validate a flash sector while leaving other sectors untouched. However, it is not possible touse one sector of the flash or the OTP to execute flash algorithms that erase or program other sectors.Special memory pipelining is provided to enable the flash module to achieve higher performance. Theflash/OTP is mapped to both program and data space; therefore, it can be used to execute code or storedata information. Addresses 0x3F 7FF0 – 0x3F 7FF5 are reserved for data variables and should notcontain program code.NOTEThe Flash and OTP wait-states can be configured by the application. This allows applicationsrunning 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 theFlash options register. With this mode enabled, effective performance of linear codeexecution will be much faster than the raw performance indicated by the wait-stateconfiguration alone. The exact performance gain when using the Flash pipeline mode isapplication-dependent.For more information on the Flash options, Flash wait-state, and OTP wait-state registers,see the "Systems Control and Interrupts" chapter of the TMS320x2806x Piccolo TechnicalReference Manual (literature number SPRUH18)
