- JC 06:46 PM PCB Development: RE: VSEL_SD functionality
- No problem. I condensed all this info into a wiki page for future reference as well. And have initiated changes for our datasheet and errata to correct the signal name.

- Thank you very much to both of you for the quick and extensive answer. The key information that the voltage of VDDSHV5 is controlled via the VSEL_SD pin might be worth putting into the datasheet. Special thanks for the pointers on the er...

- Hi Paul,
The VSEL_SD pin is connected to pin 12 of a TPS65219 PMIC on the SOM. VSEL_SD selects which voltage is applied to the AM62x VDDSHV5 voltage domain. The voltage is also present on the edge connector pin 172 as (VDDSHV_SDIO)....
