7. System Initialization On power up the CY7C656xx reads an external SPI EEPROM for configuration information At the most basic level this EEPROM has the Vendor ID VID Product ID PID and Device ID DID for the customer s application For more specialized applications other configuration options can be specified See Configuration Options on page 12 for more details After reading the EEPROM if VBUSPOWER connected to up stream Vpys is high CY7C656xx enables the pull up resistor on D to indicate its presence to the upstream hub after which a USB Bus Reset is expected During this reset CY7C656xx initiates a chirp to indicate that it is a high speed peripheral In a USB 2 0 system the upstream hub responds with a chirp sequence and CY7C656xx is in a high speed mode with the upstream D pull up resistor turned off In USB 1 x systems no such chirp sequence from the upstream hub is seen and CY7C656xx operates as a normal 1 x hub operating at full speed Enumeration After a USB Bus Reset CY7C656xx is in an unaddressed unconfigured state configuration value set to 0 During the enumeration process the host sets the hub s address and configuration After the hub is configured the full hub functionality is available Downstream Ports The CY7C656xx supports a maximum of four downstream ports each of which may be marked as usable or removable in the extended configuration 0xD2 EEPROM load or OxD4 EEPROM load
