MSP430FR5043: Ultrasonic gas meter solution, parameters configuration peoblem

Part Number: MSP430FR5043

Tool/software:

Hi,

Used for gas solution, I have some problem.

The first, I want to set USS_PGA_IN_BIAS_COUNT_SEC into 100 us , but don't take effect. And can you tell me the relationship between USS_PGA_IN_BIAS_COUNT_SEC  and USS_ULP_BIAS_DELAY.

The second, I don't know what's the meaning of USS_PGA_IN_BIAS_COUNT_SEC. TC=USS_PGA_IN_BIAS_COUNT_SEC? The meaning is the gap between T0 and TC?

The third, I know TB (above figure) is USS_TURN_ON_ADC_COUNT_SEC. it means the gap between T0 and TB?

The last, how to determine T0, reply to which register?

Looking forward to your reply, thanks!
