delineation, and passes the ATM cells to the ATM layer device. In this mode, the framer must ensure that only ATM
cells are present in the receive data stream. The M2852x performs the inverse process on transmitted data.

The M2852x has a general purpose mode interface as illustrated in
framers that do not provide frame synchronization. The M2852x receives a data stream from the external framer,
performs bit level cell delineation, and passes the ATM cells to the ATM layer device. In this mode, the framer must
ensure that only ATM cells are present in the receive data stream. The M2852x performs the inverse process on
transmitted data.

General Notes:
1. RxData is ignored when SPRxSync is asserted based on it's programmable active level. This may be used to mask
2. TxSync indicates the Start of Cell.
3. Tx and Rx are asynchronous.
