... D+ to indicate its presence to the upstream hub, after which a USB Bus Reset is expected. During this reset, CY7C65621/31 initiates a chirp to indicate that high speed peripheral USB 2.0 system, the upstream hub responds with a chirp sequence, and CY7C65621/ high speed mode, with the upstream D+ pull up resistor turned off ...

... Detection of overcurrent on downstream ports is managed by control pins connected to an external power switch device. The OVR[n]# pins of the CY7C65621/31 series are connected to the respective external power switch's port overcurrent indication (output) signals. After detecting an overcurrent condition, hub reports overcurrent condition to the host and disables the PWR# output to the external power device ...

... Configuration Options Systems using CY7C65621/31 may have the option of using a fuse ROM which is preset at the factory to configure the hub. Otherwise, it must have an external EEPROM for the device to have a unique VID, PID, and DID. The CY7C65621/31 can communicate with SPI EEPROM that are either double byte addressed or single byte with the 9th bit within the instruction byte, such as the 24LC040 parts use ...
