I/O
I/O 100M Inter-Bus port access acknowledge signal (low active). For master
hub, this pin is output; for slave hub is input, or while EXT_ARB
jumper was set to “1”, this pin is input from an external arbitration
device.
I/O 100M Inter-Bus collision signal (low active). For master hub, this pin
can output multi hub collision event to inform all slave hub ; for slave
hub, this pin is an input, or while EXT_ARB jumper was set to “1”, this
pin is input from an external arbitration device.

I/O
LED display clock signal, the signal is a discontinued clock for LED
data serial shift out. Every clock burst have 24 cycles ( period : 160 ns),
and the clock burst will be repeated with every 42ms.
