MSP430FR6043: 133 kHz transducer frequency

Danilo A.

Part Number: MSP430FR6043

Hi Team,

Section 1.2, item # 14 of the application note below stated that "The USS IP block in the MSP430FR604x devices supports transducer frequencies from 133 kHz to 2.5 MHz.". I have checked the datasheet, TRM and E2E what limits the device from driving transducers below 133kHz but I can't find the information. Can you please enlighten us why the transducer frequency is limited to 133 kHz.
