Configuration selections
The ISP1520 is configured through I/O pins and, optionally, through an external
I
2
C-bus, in which case the hub can update its configuration descriptors as a master or
as a slave.
Table 3
shows the configuration parameters.

[2]
Multiple ganged power mode is reported as individual power mode; refer to the USB 2.0 specification.
When the hub uses the global overcurrent protection mode, the overcurrent indication is through the wHubStatus field bit 1 (overcurrent)
and the corresponding change bit (overcurrent change).
9.1 Configuration through I/O pins
9.1.1
Number of downstream facing ports
To discount a physical downstream facing port, connect pins DP and DM of that
downstream facing port to V
CC
(3.3 V) starting from the highest port number (4).
The sum of physical ports configured is reflected in the bNbrPorts field.
