MSP430FR5043: "Start PPG Count(ns)" setting range

Tool/software:

HI team,

(same opportunity and related questions from the quoted E2E thread)

1. When they set "Start PPG Count" under 33,000, there are no output value of flow rate.

2. At specific relashionship in "Start PPG Count" and "GUI Based Gain Control", there are some mysterious thing. When gain is only 26, 36, or 56, it shows flow rate, but other than them, no output. In addition, when gain is 26, flow rate is output once, but there will no change after changing the reference flow rate (measured gas).

Do you have some idea to resolve this problem?

Regards,

Hayashi
