Comment on What is the limiting factor than prevents software discovery of undocumented hardware registers and instructions?
I did not know JTAG was used like this, I thought it was passive in functionality
Even for debugging jtag is quite active. It can essentially (depending on the soc or micro you’re working with) override the device and force it into specific conditions or change register values.
Very useful.
