JTAG protocol specification

Post by Gravis »

I'm making my own xmos based board that has a MCU just for XMOS JTAG but for the life of me I cannot find the JTAG protocol specification. Do anyone know where it is?

Before you ask, yes I have seen the XTAG code which is confusing as multiple abstraction layers muddles what is actually happening, has almost no comments (UGH!) and is clearly not designed to use minimal resources (my MCU: 8-bit/8KB mem /512B ram).

Thanks,
Gravis
