Buffer Memory Test/Packet Loss LED
Internally pull down. If power on or reset, LEDC (Reset function) is
keeping on and all buffer memory will be tested.
If buffer memory has
an error found, LEDB will be on.
After LEDB and LEDC off, switch self-test is done.
If packet loss
found, LEDB is keeping on 40ms within each 40ms time intervals.
