EEPROM switch (EEPROM enabled: connection between EEPROM and USB FX2 microcontroller):

Tip
For all the switches above EEPROM is enabled when the switch is ON and the EEPROM is disabled when the switch is OFF.

Tip

EEPROM switch is ON by default, to allow the USB FX2 microcontroller to read the serial EEPROM and enumerate as a custom/specific USB device.

When EEPROM switch is ON, the USB FX2 microcontroller can (re)write the (old) serial EEPROM to, for example, store a (new) custom/specific firmware.
When EEPROM switch is OFF, the USB FX2 microcontroller cannot read the serial EEPROM and enumerates as a Cypress USB generic driver. It is used for boot recovery.
