This section describes how to process the TDR register data. All of the following steps must be carried out in code.

1. Define 6x3 matrix from the table you entered in the section DP83826 TDR configuration. Then, define each column as an array and name them peak_index, peak_value, and peak_sign.
2. Initialize the following variables:
   Table 2-3 Initial Variables

   Variable	Type	Initial Value	Description
   i	int	5	Current row of the matrix
   threshold	int	10	The threshold that peak_indx must exceed for a fault to be detected
   fault_detected	bool	FALSE	Defines whether a fault has been detected
   fault_location	float	0	Fault location
   prop_dly	float		Propogation delay variable. This value can be adjusted based on the cable type. See the Prop_dly Values table for suggested values for different cable types.
   offset	int	5	Variable used in calculating the fault location.
   fault	int	0	Defines whether a fault is a SHORT (1) or an OPEN (0) fault

   Table 2-4 Prop_dly Values

   Cable type	Prop_dly
   Cat5/5e	5.35
   Cat6	5
   Cat7	4.6

3. Write a program with the following algorithm. See the TDR Algorithm Example Flow and MATLAB example code below for reference.

4. The fault type is in the Fault variable and the fault location is stored in fault_location.
