How does boundary scan work
WebSuppose that the outputs of m scan chains are to be compacted into n bits for each scan cycle with an X-compactor. The associated X-compact matrix then contains n rows and k columns, in which each row corresponds to a scan chain output (e.g., SC in Figure 3.47), and each column corresponds to an X-compactor output (e.g., Out in Figure 3.47).The entry at … WebMay 1, 2024 · The JTAG boundary scan is a bit of magic that gives you total access to the device pins without difficult soldering. It also means you can do tasks such as dumping the contents of a memory chip by simply driving the required SPI signals out the I/O pins of the microcontroller (MCU).
