System Reset
Input
RESET_N I_RST This active-low signal allows external hardware to
reset the device.
Note: The active-low pulse must be at least
5us wide. Refer to Section 8.3.2,
"External Chip Reset (RESET_N)," on
page 35 for additional information.

LED 0 Output LED0 O8 General purpose LED 0 output that is
configurable to blink or “breathe” at various rates.
Note: LED0 must be enabled via the Protouch
configuration tool.

Detect
Upstream
VBUS Power
VBUS_DET IS Detects state of upstream bus power.
When designing a detachable hub, this pin must
be connected to the VBUS power pin of the
upstream USB port through a resistor divider
(50kΩ by 100kΩ) to provide 3.3V.
For self-powered applications with a permanently
attached host, this pin must be connected to
either 3.3V or 5.0V through a resistor divider to
provide 3.3V.
In embedded applications, VBUS_DET may be
controlled (toggled) when the host desires to
renegotiate a connection without requiring a full
reset of the device.

Remote
Wakeup
Indicator
SUSP_IND OD8 Configurable sideband signal used to indicate
Suspend status (default) or Remote Wakeup
events to the Host.
Suspend Indicator (default configuration):
0 = Unconfigured, or configured and in USB
suspend mode
1 = Device is configured and is active
(i.e., not in suspend)
For Remote Wakeup Indicator mode:
Refer to Section 8.5, "Remote Wakeup Indicator
(SUSP_IND)," on page 36.
Refer to Section 6.3.1, "Non-Removable Device
(NON_REM[1:0])," on page 28 for information on
LED polarity when using this signal.
Local Power
Detect
LOCAL_PWR IS Detects the availability of a local self-power
source.
0 = Self/local power source is NOT available.
(i.e., device must obtain all power from upstream
USB VBUS)
1 = Self/local power source is available

High Speed
Indicator
HS_IND O8 Indicates a high speed connection on the
upstream port. The active state of the LED will be
determined as follows:
If CFG_SEL1 = 0, HS_IND is active high.
If CFG_SEL1 = 1, HS_IND is active low.
Asserted = hub is connected at high speed
Negated = Hub is connected at full speed
