RSTN asserted: 500 k

Ω PD

No function. Leave floating.

ENA_HS

9

O

RSTN asserted: 500k

Ω PD

Flag indicating that channel is in High Speed mode. Asserted upon:

1.

Detection of USB-IF High Speed test fixture from an unconnected

state followed by transmission of USB TEST_PACKET pattern.

2.

Squelch detection following USB reset with a successful HS

handshake [HS handshake is declared to be successful after single

chirp J chirp K pair where each chirp is within 18 µs – 128 µs]

De-asserted upon detection of disconnect or suspend.

Can be left floating if not needed.

O

RSTN asserted: 500 k

Ω PD

Flag indicating that a USB device is attached.

Asserted from an unconnected state upon detection of DP or DM pull-up

resistor.

De-asserted upon detection of disconnect.

Can be left floating if not needed.
