What is the minimum Frequency of the PWM Outputs?
Background; Fan connection allows 10-16Hz PWM for powering the fan and need a capture interface for speed signal of the fan.

Thorsten,
PWM frequency information can be found under TRM (https://www.ti.com/lit/zip/spruil1) Section 12.4.2.4.9.5 Operational Highlights for the High-Resolution PWM Submodule. Note, FICLK is typically 125 MHz.
Thanks & Regards,
