Notes:
1.
Functional and tested operating conditions are given in Table 4. Absolute maximum ratings are stress ratings
only, and functional operation at the maximums is not guaranteed. Stresses beyond those listed may affect device
reliability or cause permanent damage to the device.
2.
Caution: Vin must not exceed OVDD or GVDD by more than 0.3 V at any time including during power-on reset.
3.
Caution: OVDD/GVDD must not exceed VDD/AVDD by more than 2.0 V at any time including during power-on
reset.
4.
Caution: VDD/AVDD must not exceed OVDD/GVDD by more than 0.4 V at any time including during power-on
reset.
5.
Vin may overshoot/undershoot to a voltage and for a maximum duration as shown in Figure 2.
6.
BVSEL must be set to 0, such that the bus is in 1.8 V mode.
7.
BVSEL must be set to HRESET or 1, such that the bus is in 2.5 V mode.
8.
L3VSEL must be set to ¬HRESET (inverse of HRESET), such that the bus is in 1.5 V mode.
9.
L3VSEL must be set to 0, such that the bus is in 1.8 V mode.
10. L3VSEL must be set to HRESET or 1, such that the bus is in 2.5 V mode.
