3.5.4 Fapi_remapEccAddress()

Takes ECC address and remaps it to main address space

Synopsis

uint32 Fapi_remapEccAddress(
         uint32 u32EccAddress)

Parameters

u32EccAddress [in] ECC address to remap

Description

This function returns the main array Flash address for the given Flash ECC address. When the user wants to program ECC data at a known ECC address, this function can be used to obtain the corresponding main array address. Note that the Fapi_issueProgrammingCommand() function needs a main array address and not the ECC address (even for the Fapi_EccOnly mode).

Return Value

  • 32-bit Main Flash Address
  • 0xFFFFFFFF if the Flash ECC address provided is invalid
