Figure 8–8
SAMPLE/PRELOAD instruction code shifts in through the TDI pin. The TAP controller
advances to the CAPTURE_DR state and then to the SHIFT_DR state, where it remains if
TMS is held low. The data shifted out of the TDO pin consists of the data that was
present in the capture registers after the capture phase. New test data shifted into the
TDI pin appears at the TDO pin after being clocked through the entire boundary-scan
register.
