MM9Z1x638 System calibration

cui1 — Fri, 08 Dec 2023 08:57:06 GMT

When I read the summary 5.6 of the System Calibration section of Chapter V of AN12301, I see IFR_COMP_VSG_VSENSE2:518 (206h) and IFR_COMP_VO_VSENSE2: −25 (E7h) Can you tell me how these two values were obtained so that I can refer to them in later calibration

Thanks for your answer

Dear Yuhe,

the values are from the IFR content table. From the COMP_VSG_VSENSE2 and COMP_VO_VSENSE2 registers. Please refer to the section 6.3.3.5.1 in the MM9Z1_638D1 datasheet.

With Best Regards,

Jozef

Yeah, I saw them in the datasheet, and I was thinking about how to use them in my software program. Is the macro definition called directly? Thank you for your answer!

The code in this formula corresponds to whether IFR_COMP_VO_VSENSE2

[A] Yes, this is correct. Please refer to the section 3.1 in the AN12301 and to section 6.3.3.5.1 in the MM9Z1_638D1 datasheet.
