Figure 8. TSU6721EVM GUI Showing Manual Switching Mode
According to page 23 of the TSU6721 datasheet, the TSU6721 is now in manual switching mode.
Attach VBUS or a valid ID resistance to the TSU6721EVM. The attachment will not determine the
switch status, but it will ensure that the TSU6721 does not enter sleep mode, allowing manual
switching to work properly.
9. Connect an ohmmeter between DM (J14) and DM_HT (J11), and connect another ohmmeter between
DP (J13) and DP_HT (J10).
