Manufacturer:ON Description:During the power-up sequence, internal logic of the SX2 checks for the presence of an I2C EEPROM.[1,2] If it finds an EEPROM, it will boot off the EEPROM. When the presence of an EEPROM is detected, the SX2 checks the value of first byte. If the first byte is found to be a 0xC4, the SX2 loads the next two bytes into the IFCONFIG and POLAR registers, respectively. If the fourth byte is also 0xC4, the SX2 enumerates using the descriptor in the EEPROM, then signals to the external master when enumeration is complete via an ENUMOK interrupt (Section 3.4). If no EEPROM is detected, the SX2 relies on the external master for the descriptors. Once this descriptor information is receive from the external master, the SX2 will connect to the USB bus and enumerate. |
