I Master hub selection:
Descriptions
when high: means hub internal inter_bus arbiter is enabled and hub
internal two_port switch is well conneted to 10M_hub core and
67
100M_hub core .
IACKB10
when low: means hub internal inter_bus arbiter is disabled and hub
internal two_port switch is not connected to 10M_hub core and
100M_hub core.
I/O 10M Inter-Bus port access acknowledge signal (low active). For master
84
hub, this pin is output; for slave hub is input, or while EXT_ARB
jumper was set to high, this pin is input from an external arbitration
device.
ICOLB10
I/O 10M Inter-Bus collision signal (low active). For master hub, this pin can
85
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 high, this pin
is input from an external arbitration device.
