CRC-4 Sync

Hi, CRC is Cyclic Redundancy Check, for detecting and correcting errors on frames. I've copied this from the manual to illustrate:
'When the CRC-4 error checking scheme is used, a CRC bit is encoded as the first position of all the even-numbered frames. CRC-4 is a 4-bit error detection code. Each 16-frame cycle contains two CRC-4 error codes. When CRC-4 is not used, the first-bit of even-numbered frames is unassigned.' |-I
Hope this helps.
