After detecting an overcurrent condition, hub reports overcurrent condition to the host and disables the PWR# output to the external power device. Document Number: 38-08037 Rev. *T CY7C65620/CY7C65630 The polarity of the OVR pins can be ...

Page 7

Port Indicators The USB 2.0 port indicators are also supported directly by CY7C65620/CY7C65630. According to the specification, each downstream port of the hub optionally supports a status indicator. The presence of indicators for downstream facing ports is specified by bit ...
