Hello team,
Previously I've asked about TDO toggle mechanism, see above history.
My customer returned a unit that I can observe the TDO toggle on them. However our FA report concluded the unit was TNI (trouble not found). So my question is, what kind of self-test the chip performs at initialization and on what condition it outputs TDO toggle? Because from previous discussion when a unit toggles TDO, that means it is unrecoverable.
thanks,
Jo
