MULTI-PHY USER NETWORK INTERFACE

PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE

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.
