Web11 apr. 2024 · Introduction. Check out the unboxing video to see what’s being reviewed here! The MXO 4 display is large, offering 13.3” of visible full HD (1920 x 1280). The entire oscilloscope front view along with its controls is as large as a 17” monitor on your desk; it will take up the same real-estate as a monitor with a stand. Web6.3.2 Adding TAPs to the Scan Chain. After the “defaults” are set up, add the TAPs on each chip to the JTAG scan chain. See TAP Declaration, and the naming convention for taps. In the simplest case the chip has only one TAP, probably for a CPU or FPGA. The config file for the Atmel AT91SAM7X256 looks (in part) like this:
