Receive Multiframe Sync Pulse (RxCRCSYNCn):

The RxCRCSYNCn pins are used to indicate the receive multi-

frame boundary. These pins pulse "High" for one period of

RxSERCLK when the first bit of an inbound DS1/E1 Multi-frame

is being output on the RxCRCSYNCn pin.

• In DS1 ESF mode, RxCRCSYNCn repeats every 3ms

• In DS1 SF mode, RxCRCSYNCn repeats every 1.5ms

• In E1 mode, RxCRCSYNCn repeats every 2ms.
