Hello,
The description of the BGDR field given in Table 19 seems to indicate that:
- A BGDR value of 0x1F should correspond to an on-chip reference voltage of 0.84 V.
- A BGDR value of 0x20 should correspond to an on-chip reference voltage of 1.24 V.

Therefore on Figure 33 I would expect to see:
- 0.84 V on the vertical axis corresponding to 31 (0x1F) on the horizontal axis
- 1.24 V on the vertical axis corresponding to 32 (0x20) on the horizontal axis
However, Figure 33 seems to show:
- 0.84 V corresponding to 32
- 1.24 V corresponding to 31

I therefore suspect that the description of BDGDR in Table 19 is incorrect.
Please let me know if my reasoning is correct.
Kind regards,
DB
