2.2 Configuration Jumpers

Multiple jumpers are provided on the EVM for configuration of TUSB1004 and also for probe points.

Following is a list of 4-level jumpers which are used to configure the TUSB1004: JMP3, JMP4, JMP5, JMP6, JMP7, JMP8, JMP9, and JMP10. The jumper position to select between the different levels is detailed in 4-Level Configuration Jumper Settings Table.

Note: 4-level pins are sampled on rising edge of the EN pin. Therefore, a change in any 4-level pin state will not be applied until after the EN pin is toggled from low to high.
