Configuration Switches
The TUSB217 has three switches to facilitate configuration changes. Changing these switch settings
without a complete understanding of the result is not recommended. Configuration inputs are only read by
the TUSB217 during power on reset or after de-asserting the RSTN pin, changing these switch settings
while the EVM is powered on has no effect. Refer to the device datasheet for detailed pin descriptions and
functionality along with EVM schematic for additional information.
The switch definitions are as follows:
SW1 RSTN Pushbutton Switch:
•
Pushbutton to place TUSB217 device in RESET
•
Release to de-assert RESET
SW2 BOOST:
1. Sets TUSB217 to BOOST Level 1
2. Sets TUSB217 to BOOST Level 3
3. Sets TUSB217 to BOOST Level 2
Shunt across J3 Sets TUSB217 to BOOST Level 0
SW3 RX SEN:
1. Pull Up (High Boost)
2. NC (Mid Boost)
