Note 5. All voltages with respect to ground.
Note 6. AVSS, DVSS, VSSL and VSSR must be connected to the same analog ground plane.
Note 7. Max value of VIND is lower either of (TVDD + 0.3) or 6.0V.
WARNING: Operation at or beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.

Note 9. TVDD and AVDD must be connected to the same ground plane and powered up at the same time.
When not using the LDO (LDOE pin = “L”), all power supplies (DVDD (1.8V), TVDD and AVDD
(3.3V) and VDDL/R (5V)) should be powered up at the same time or sequentially in the order of
3.3V (TVDD, AVDD), 1.8V (DVDD) and 5V (VDDL/R).
Note 10. The internal LDO outputs DVDD (1.8V) when the LDOE pin = “H”. 3.3V (TVDD and AVDD)
power supplies must be powered up before or at the same time with 5V (VDDL/R) power
supplies when the LDOE pin = “H”.
