I'm trying to program DCDC3 to 1.5V output and am unsure of the resistor value to select for the DC34_SEL pin.
According to the datasheet it should be 20kOhm (with a maximum of 22kOhm):
According to the AM437x GP EVM it's 22kOhm
A couple of questions:
1. Wouldn't a 22kOhm resistor violate the recommended values given resistor tolerances?
2. If not, would a 22.1kOhm (1%) resistor function fine in this case?
3. I notice that there's a grey area between default values. Are there additional default values that can be programmed in between these area? For example, suppose we use 26.45 kOhm, what would be programmed defaults?
