Hello Sadatan Vashistha,
The ONOFF Pin is on the VDD_SNVS_IN power domain and is a GPIO ball type, so according to the datasheet on table 24 (Single Voltage GPIO DC Parameters), it would be:
| Parameter | Symbol | Test Conditions | Min | Max | Units |
|---|
| High-Level input voltage | VIH | — | 0.7 × OVDD | OVDD | V |
| Low-Level input voltage | VIL | — | 0 | 0.3 × OVDD | V |
Where OVDD would be VDD_SNVS_IN.
I hope this helps!
Regards,
