7.2.5 Dual Voltage I/Os  
The device supports dual voltages on some of its I/Os. These I/Os are partitioned into the following  
groups, and each group has its own dedicated supply pins: DVDD, DVDD_GPMC, DVDD_C, and  
DVDD_SD. The supply voltage for each group can be independently powered with either 1.8 V or 3.3 V.  
For the mapping between pins and power groups, see Section 3.3, Terminal Functions of the datasheet.  
In addition, the I/O voltage on the DDR interface is independently selectable between 1.35 V, 1.5 V or  
1.8 V to support various DDR device types.  
7.2.6 I/O Power-Down Modes  
On the device, there are power-down modes available for the following PHYs:  
Video DACs  
DDR  
USB  
HDMI  
CSI2  
PCIE  
When a PHY controller is in a power domain that is to be turned "OFF", software must configure the  
corresponding PHY into power-down mode, prior to putting the power domain in the "OFF" state.
