5. APPENDIX A: CS8406 TCBL CONNECTION FOR THE CDB8421 REV. A

Pin 15 of U19 on the CDB8421 Rev. A has been lifted. This eliminates the connection to the

TCBL pin on the CS8406 part. The pin should remain lifted and no connection to the pin should

be reestablished for the board to operate properly. Changes have been made to CDB8421

Rev. B boards so that the pin need not be lifted.
