Signal levels on the DP and DM pins are determined by other USB devices and external pull-up or pull-down resistors.
In suspend mode (SUSPEND = HIGH), the differential receiver is inactive and output RCV is always LOW. The resume signaling is
detected through single-ended receivers VP/VPO and VM/VMO.
