ID:98004 Parameter error: illegal value for LPM_SHOWAHEAD parameter of a FIFO buffer

CAUSE: You set the LPM_SHOWAHEAD parameter of a FIFO buffer to an illegal value; however, the value of the LPM_SHOWAHEAD parameter must be ON or OFF. This error usually occurs when you instantiate a megafunction directly in a text file rather than using the MegaWizard Plug-In Manager .

ACTION: Change the value of the LPM_SHOWAHEAD parameter to ON or OFF. To avoid receiving this message in the future, Intel recommends using the MegaWizard Plug-In Manager.
