You are of course right. Possibly when I first read about "Digital Thermal
Sensor", things may have been different. But I'm sure everyone knew what I
meant.

For example on a Pi, `vcgencmd measure_temp` works, though strictly speaking that measures the general temp of the SoC - which like many devices that are ARM powered is a large thing to do stuff and just happens to have a few Gips of processor hidden in a small corner.

Exactly what temperature is being measured probably doesn't matter as long
as there is enough range to help add some entropy.
