7.3.8 Board Level Test Support

The in-circuit tristate enable signal (ICTSEN) is a board level test control signal. By driving ICTSEN to a logic high state, all controller outputs (except TDO1 and TDO2) are tristated.

The DLPC4420 controller also provides JTAG boundary scan support on all I/O except non-digital I/O and a few special signals. #GUID-7E7B61AC-7CB5-4201-B1D4-734ED225B558/T4322339-39 defines these exceptions.
