Receiver Output. Single-ended CMOS output. RCV responds to the differential
input on D+ and D- (see Table 3).
System-Side Data Input/Output. Drive OE high to make VP a receiver output.
Drive OE low to make VP a driver input (see Table 3).
Mode Control Input. Selects single-ended (mode zero) or differential (mode one)
input for the system side when converting logic-level signals to USB-level
signals. If MODE is forced high, mode one is selected. If MODE is forced low,
mode zero is selected (see Table 3).
System-Side Data Input/Output. Drive OE high to make VM a receiver output.
Drive OE low to make VM a driver input (see Table 3).
Output Enable. Drive OE high to enable the receiver. Drive OE low to enable the
driver input.
Enumerate Input. Drive ENUM low to disconnect the internal 1.5kΩ resistor, and
enumerate the USB. With ENUM high, the internal 1.5kΩ resistor is connected to
either D+ or D-, depending on the state of SPEED.
