hi everyone:
i have a question met in my debug, using TM4C1294KCPDT, designed a board for my company, for LED in RJ45, i use LED0 for link status, LED1 for RXTX activity, when there is data go out or in, it will flash. all the function goes well, except one:
when the board is sending data out to PC, during that process, when i plug off the netcable in sudden, the LED0 goes off immediately, but LED1 will still flash for next few seconds.
it abnormal for LED1, when netcable off, it should go off permantly, why it will flash for next few second? and it will only flash only i am sending data out.
have u seen this? is this normal?
