Hi, just for reference: doing the math based on the Sapphire board
schematic, the values for vdd_log are:
|------|-------|
| PWM | Volts |
|------|-------|
| Hi-Z | 1.136 |
| 0% | 1.356 |
| 100% | .9167 |
|------|-------|
The datasheet states that the acceptable range for vdd_log is 0.8 .. 1.0
So, an option could be to configure GPIO1_C3 as output high and vdd_log
would be at the range's center.
Aside from math on paper, it has been tested. Setting GPIO1_C3 as output
high gives a vdd_log of 0.922 measured volts and the board, so far, works
fine.
Regards,
Vicente.

The datasheet states that the acceptable range for vdd_log is 0.8 .. 1.0
So, an option could be to configure GPIO1_C3 as output high and vdd_log
would be at the range's center.
Aside from math on paper, it has been tested. Setting GPIO1_C3 as output
high gives a vdd_log of 0.922 measured volts and the board, so far, works
fine.
Regards,
Vicente.
