PWM is for driving a heater, not for measuring temperature. Can't say about Marlin either, but Teacup code is here:

Heater PID and PWM output: [github.com] Quite a bit of code, because it deals with _all_ PWM outputs on any variant of ATmega. Many repeating patterns, though. For PWM only, heater_init() and heater_set() are sufficient.

Analog readings: [github.com]
Translating analog readings into temperatures: [github.com]
