I/O
O Stop. USB n _STP indicates the end of a transfer on the bus.
O Port control 0. USB n _PCTL0 controls the port status indicator LED 0 when in host mode.
O Port control 1. USB n _PCTL1 controls the port status indicator LED 1 when in host mode.

to USB port, it drives USB n _DIR high to take ownership of the bus. When the PHY has no data
to transfer it drives USB n _DIR low and monitors the bus for link activity. The PHY pulls
USB n _DIR high whenever the interface cannot accept data from the link.
to the PHY, USB n _NXT indicates when the current byte has been accepted by the PHY. The
USB port places the next byte on the data bus in the following clock cycle. When the PHY is
sending data to USB port, USB n _NXT indicates when a new byte is available for USB port to
consume.
Power fault. USB n _PWRFAULT indicates whether a power fault occurred on the USB port
Vbus.
Note: USB n _PWRFAULT, only exists for USB1 and USB2, not for USB3.
Note: USB n _PCTL0, only exists for USB1 and USB2, not for USB3.
Note: USB n _PCTL1, only exists for USB1 and USB2, not for USB3.
Direction. USB n _DIR controls the direction of the data bus. When the PHY has data to transfer
Next data. The PHY asserts USB n _NXT to throttle the data. When USB port is sending data

Asserted—PHY has data to transfer to the link.
Negated—PHY has no data to transfer.
Asserted—PHY is ready to transfer byte.
Negated—PHY is not ready.
Asserted—USB asserts this signal for 1 clock cycle to stop the data stream
Negated—Indicates normal operation.
Asserted—Indicates that a Vbus fault occurred. Applications that support power
Negated—Indicates normal operation.
Asserted—LED on.
Negated—LED off.

currently on the bus. If USB port is sending data to the PHY, USB n _STP
indicates the last byte of data was previously on the bus. If the PHY is
sending data to USB port, USB n _STP forces the PHY to end its transfer,
negate USB n _DIR and relinquish control of the data bus to the USB port.
