Reading analog pin while boundary scanning

ronit over 5 years ago

Hii everyone,

I'm just starting to boundary scanning methods. After seeing a diagram in one of your blog, I come to know that there is a scan cell between register and actual pin, from where we can see the state of a pin whether it is high or low by checking at scan cell. But what if it is analog pin. does it has its own ADC?

This is SoC specific (which?) so I suggest you to ask this in a forum for your SoC.

As I wrote before: I recommend to ask SoC specific questions in a forum for the SoC, here stm32. This is a core forum.

CoreSight is Arm, but whether or not the pins can be scanned and if, how depends on the manufacturer of the SoC. I guess the info you seek will be noted in some of the manuals.
