The value of IfClockEdge influences the (internal) active clock edge(s) for generating/sampling data on the serial line. This value should be left on DEFAULT under normal circumstances. Nevertheless, in some rare cases it is possible the connection does not work properly. This behaviour may be produced by timing inconsistencies over the serial line in conjunction with some disadvantageous clock/data processing at the DTE/DCE devices and is very device couple specific. The several settings allow shifting data generation/sampling by half a cycle of the incoming serial clock. The variation of this setting can help to make a not working connection working. A typical sign for an erroneous situation in this sense is the reception of massive corrupted frames at one or both communication end points. default(1) the clock edges for generating/sampling are the default ones rxc-inverted(2) the receiver's data sampling is shifted by half a cycle of incoming serial clock (currently only supported by X8500) txc-inverted(3) the transmitter's data generation is shifted by half a cycle of incoming serial clock rxc-txc-inverted(4) both the receiver's data sampling and the transmitter's data generation is shifted by half a cycle of incoming serial clock (currently only supported by X8500)
