93 / 293 page  PM7344 S/UNI-MPH DATA SHEET PMC-950449 ISSUE 6 MULTI-PHY USER NETWORK INTERFACE PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE 77 RUNI: When the T1 or E1 format is selected, the RUNI bit enables the interface to receive uni-polar digital data and line code violation indications on the multifunction pins RDP/RDD[x] and RDN/RLCV/ROH[x]. When RUNI is set to logic 1, the RDP/RDD[x] and RDN/RLCV/ROH[x] multifunction pins become the data and line code violation inputs, RDD[x] and RLCV[x], sampled on the selected RCLKI[x] edge. When RUNI is set to logic 0, the RDP/RDD[x] and RDN/RLCV/ROH[x] multifunction pins become the positive and negative pulse inputs, RDP[x] and RDN[x]. If RUNI is set to logic 1, the DCR bit in the CDRC Configuration Register must also be set to logic 1. The RUNI bit is ignored if either the J2 or Arbitrary framing formats are selected. RFALL: The RFALL bit enables the Receive Interface to sample the multifunction pins on the falling RCLKI[x] edge when clock recovery is disabled. When RFALL is set to logic 1, the interface is enabled to sample the RDP/RDD[x] and RDN/RLCV/ROH[x] inputs on the falling RCLKI[x] edge. When RFALL is set to logic 0, the interface is enabled to sample the inputs on the rising RCLKI[x] edge. |
