4.6.1 Flash API

F28004x has two Flash banks. F28002x has only one Flash bank. Hence, the F28002x Flash API library (FlashAPI_F28002x_FPU32.lib) supports erase, program and verify operations only for the Flash Bank0 address range. Compared to the F28004x Flash API library (F021_API_F28004x_FPU32.lib), the F28002x Flash API is enhanced to return an error when an invalid address is provided for erase, blank-check, program and verify functions. Also, the F28002x Flash API is enhanced to return an error when an invalid programming mode is provided for program operation. Fapi_getLibraryInfo() in FlashAPI_F28002x_FPU32.lib returns the Flash API minor version as 57 (F28004x Flash API returns 56 as the API minor version). The F28002x Flash API library is compiled for EABI format, whereas, the F28004x Flash API library is compiled for legacy COFF. F28002x Flash API size is approximately 5.5KB. Note that F28004x and F28002x have the same Bank0 memory map and sector sizes. Also, the Flash wait-state configuration requirement is the same between the two devices. Hence, the F28002x Flash API version is chosen as 1.57.00.00, an update of F28004x Flash API V1.56.01.00. These features are summarized in Table 20
