RM0511 Rev6: LCSC register map (Table 38) missing VDD12o power domain color highlighting

[Steave]

Hello,

I would like to report a documentation issue in RM0511 Rev6, section 15.9 (LCSC register map, Table 38).

The introductory text states:

> "The green cells indicate the register is in the VDD12o power domain. This implies those registers are not reset on Deepstop exit."

However, in Rev6 the color highlighting is missing from the table — it is not possible to identify which LCSC registers are in the VDD12o power domain. This information is critical for correct Deepstop/low-power mode implementation, as registers in the VDD12o domain retain their values across Deepstop while others do not.

 

**References:**
- RM0511 Rev6, section 15.9, Table 38
- RM0511 Rev5, section 15.9, Table 39

Thank you.

Hello ​@Steave ,

First let me welcome you to the STM32 Community and thank you for having reported this.

I escalated this request to involved people (through Internal ticket number: CDM0063478) for further review.

Hello Steave, 

this is a regression. 

The behavior remains the same as per Rev5: all but LCSC_VER and LCSC_ISR registers are retained.

BR,
Filippo

Hello Filippo,

Thank you for the clarification — it is helpful to know that all LCSC registers except LCSC_VER and LCSC_ISR are retained across Deepstop.

Just to note: the only version currently available for download on the official ST website is RM0511 Rev6, which is still missing the color highlighting in Table 38. This makes it unnecessarily difficult for developers to identify which registers are in the VDD12o power domain when working from the official documentation.

Thank you.

Hello Steave,

indeed, thanks to your input, we have noted this regression and in the next revision of the RM0511 it will be fixed.

Thanks!
Filippo
