AM5728: ABB questions

Guru 10235 points
Part Number: AM5728


Hello, TI Experts,

 

Our customer sent us some questions about Adaptive Body Biasing (ABB) of AM5728

from TRM(SPRUHZ6H) "18.4.6.13 ABB Associated Registers".

 

Question:

   - When should be configured ABB Registers?

   - If frequency and OPP are not changed after booting, is ABB register setting once enough after booting?

 

Best regards
