Hello.I want to complement example code msp430fr6043_sdhs_01__, but have a problem with understending SHDS_PWR_UP in MSP430FR58xx, MSP430FR59xx, and MSP430FR6xx Family User's Guide.How to check in CSS whether this command exists and how it affects the SDHS operation?

Hello,

I don't fully understand the question. Figure 18-2 shows the sources of the internal SHDS_PWR_UP signal. https://www.ti.com/lit/ug/slau367p/slau367p.pdf?ts=1591238629251

Please let me know if the signal helped explain how to control the signal.

Thanks.

I want to add print of LEA information in console. But LEA hasn`t values from SDHC(ADC of MCU module USS). I can`t understand why it is happening.
Suggest that is problem with SHDS_PWR_UP, but tangle. Registers work correct and test by Water Flow Meter Quick Start Guide successfully.

Hello,

I think you are asking how to control the SHDS_PWR_UP signal. This appears to be an internal signal that is not controlled directly.

Section 22.2.6 shows how the SHDS_PWR_UP signal is being controlled by the available control bits you do have.

Hope this helps.
