DLPS117B July 2018 – October 2020 DLPC6421
The in-circuit tri-state enable signal (ICTSEN) is a board level test control signal. By driving ICTSEN to a logic high state, all DLPC6421 outputs (except TDO1 and TDO2) will be tri-stated.
The DLPC6421 controller also provides JTAG boundary scan support on all I/O except non-digital I/O and a few special signals. Table 7-4 defines these exceptions.
