Flash: Minimum Programming Word Size
B, C
The Main Array flash programming must be aligned to 64-bit address boundaries and each 64-bit word may only be programmed once per write/erase cycle.
Applications using Fapi_issueProgrammingCommand() in Fapi_AutoEccGeneration or Fapi_DataAndEcc modes are implicitly performing 64-bit programming since ECC is programmed for each 64 bits. Applications using Fapi_DataOnly mode with fewer than 64 bits may be impacted by this advisory.
The DCSM OTP programming must be aligned to 128-bit address boundaries and each 128-bit word may only be programmed once. The exceptions are:
All applications should follow the restrictions outlined in this advisory. Contact TI for devices already in production which violate this advisory.
