Fapi_issueFsmSuspendCommand()

Issues Flash State Machine suspend command

Synopsis

Fapi_StatusType Fapi_issueFsmSuspendCommand(void)

Parameters

None

Description

This function issues a suspend now command which will suspend the FSM commands, Program and Erase Sector, when they are the current active command. Use Fapi_getFsmStatus() to check to see if the operation is successful. A bank erase command cannot be suspended, and will return an error indicating failure.

Return Value

  • Fapi_Status_Success (success)
  • Fapi_Error_Fail (Failure, in case bank erase is the current active command)
