SUSPEND

I/O

Hub suspend status indicator. This pin is asserted if both the SS and

USB 2.0 hubs are in the suspend state and is de-asserted when either

of the hubs comes out of the suspend state.

1.2 V core supply

VBUS _US

PWR

CYUSB3324/3328: Connect the VBUS_US pin to the local 5 V supply.

If ACA-Dock mode is disabled using Configuration Options on page 24,

this pin must be connected to VBUS from US port.

Other part numbers: This pin must be connected to VBUS from US port.

VBUS_DS

PWR

This pin is used to power the Apple-charging circuit in HX3.

For BC v1.2 compliance testing, connect pin to GND. For normal

operation, connect pin to local 5 V supply.

USB Precision Resistors

RREF_USB2

Connect pin to a precision resistor (6.04 k

 ±1%) to generate a current

reference for USB 2.0 PHY.

RREF_SS

Connect pin to a precision resistor (200

 ±1%) for SS PHY termination

impedance calibration.
