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

1. Define 5x3 matrix as shown in Table 2-3. Then, define each column as an array and name them peak_index, peak_value, and peak_sign.
   Table 2-3 5x3 Matrix Format

   peak_index	peak_value	peak_sign
   0190[7:0]	019a[7:0]	01a5[0]
   0190[15:8]	019a[15:8]	01a5[1]
   0191[7:0]	019b[7:0]	01a5[2]
   0191[5:8]	019b[15:8]	01a5[3]
   0192[7:0]	019c[7:0]	01a5[4]

2. Initialize the following variables:
   Table 2-4 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
   threshold2	int	24 or 17	The threshold that peak_indx must exceed for a fault to be detected for the first two iterations. DP83867: threshold2 = 24 DP83869: threshold2 = 17
   fault_detected	bool	FALSE	Defines whether a fault has been detected
   fault_location	float	0	Fault location
   prop_dly	float		Propogation delay variable, depends on the cable type and EVM. See the Prop_dly Values table for more information.
   offset	int	16	Variable used in calculating the fault location
   fault	int	1	Defines whether a fault is a SHORT (1) or an OPEN (0) fault

   Table 2-5 Prop_dly Values

   Cable type	Prop_dly (DP83867)	Prop_dly (DP83869)
   Cat5/5e	5.35	5.1
   Cat6	5	5
   Cat7	4.6	4.6

3. Write a program with the following algorithm. See the MATLAB example code for reference.
   Figure 2-1 DP83867 and DP83869 TDR Algorithm
4. The fault type is in the Fault variable and the fault location is stored in fault_location.
