The JTAG and Emulation signals are in same power domain. The TDI, TDO, TCK, TMS, TRSTn, EMU0 and EMU1 signals are powered by the VDDSHV_MCU (Dual-voltage IO) supply rail (IO supply for IO group MCU). VDDSHV_MCU can be configured either 1.8 V or 3.3 V.
For proper implementation of the JTAG interface, refer the Emulation and Trace Headers Technical Reference Manual and XDS Target Connection Guide.
