EN User-Defined Pattern Command 13-19
User-defined Pattern Example
This example shows how the user-defined pattern command is used
to create a user-defined patterns. For this example, a pattern of
triangles is used. The first step is to design the base pattern triangle
(in this case, using 64 bytes of data). The base pattern binary data is
shown below:
11111111111111111111111111111111
01111111111111111111111111111110

00000000000000011000000000000000
This translates into the following 64 bytes in hexadecimal values:
