Low power status output. This pin will be asserted whenever the V1410
device is placed into the suspend state.
This pin is sampled momentarily at power-up or at any USB bus reset to
configure the polarity of the LOWPOWER output during suspend mode.
An external (10K) pull-up resistor will cause the LOWPOWER pin to be
asserted HIGH during suspend mode. An external (3.3K) pull-down resis-
tor will cause the LOWPOWER pin to be asserted LOW during suspend
mode.
USB port differential data plus. This pin has a 1.5 K Ohm internal pull-up
resistor.
USB port differential data minus.

EEPROM can be used to store default configurations upon power-up
including the USB Vendor ID and Device ID. See
resistor (typically 4.7 to 10 KOhms) is required.
If an EEPROM is not used, this pin can be used with the SCL pin to
select the Remote Wake-up and Power modes. An external pull-up or
pull-down resistor is required. See
