(3) Error freeze
When a J.NET module detects a hardware error, the ERR LED turns on, and error freeze information
is saved. The J.NET module then stops operating.
Figure 13-13 shows the format of the error freeze information. For information about error codes and
the stack frame in the following format, see the following pages.
