C6748 nor eeprom booting

C6713 had a dedicated eeprom busy/ready pin, and we are working on a new design using C6748. Not sure how to replace this functionality on the new part?

Is this a parallel EEPROM? If so, I believe you're looking for the WAIT pin on the EMIF.

To provide additional color to Brad's inputs, the C6713B implemented an EMIF - Asynchronous/Synchronous Memory Control module as indicated in the Terminal Functions of the TMS320C6713B datasheet. The associated "busy/ready" signal was called ARDY.

On the TMS320C6748, the similar interface is the EMIF A and the similar functionality signal is EM_WAIT[0] and EM_WAIT[1].
