Hi Expert,

My customer wants to generate 0.5Hz and 100 Hz PWM dynamically.

currently, i only can generate lowest 3HZ frequency.

any idea how to do it or how to change clock source to low frequency crystal.

Please see the following post regarding changing the clock source:

(53) CCS/CC1312R: Clock source for general purpose timer - Sub-1 GHz forum - Sub-1 GHz - TI E2E support forums

Not sure if the lower frequency is a limitation in the PWD driver only, and if you are able to get a lower frequency if you implement pwm yourself using our timer drivers directly.
