As shown in Figure 2-6, the application requires two sets of power profiles per port: corresponding 30W
and 60W PDOs. In this step, generate these configurations and map them to virtual
Change Number of
Configuration Sets in General Settings to four.
Rename Configuration Set as
shown below for convenience.
Virtual Address 1
-> Port-0 30W
Virtual Address 2
-> Port-0 60W
Virtual Address 3
-> Port-1 30W
Virtual Address 4
-> Port-1 60W
Now, map Configuration sets
to Virtual Address as shown in Figure 2-8.

Sets and Map to Virtual Address
Note: Do not
use address 0x00 and 0x04 as they are reserved for port
The App configuration register (0x6C) holds the
index pointing to the application configuration that needs to be loaded when the
GPIO assert/ de-assert and also holds the command channel interface for executing
the PD message task. In this step, modify Port-0 App Configuration Register
to point to the application configuration index Virtual Address 1 on GPIO
high transition (corresponding to application configuration Port-0 30W) and point to
Virtual Address 2 on GPIO high transition (corresponding to application
configuration Port-0 60W) and then execute SSrC task using CMD1 channel.
Click the Port 1
Click the App
The index of configurations
that need to be loaded on GPIO low/high transition are selected from the
drop-down menu below Value tab.
The default command channel
CMD1 (0x08) can be used for executing PD message task.
Select PD message task
SSrC from the drop-down menu to transmit the Source Capability
configured in the application configuration space indexed by Virtual Address
1 or Virtual Address 2. Enter !CMD in not Task field to
indicate no action.
Figure 2-9 App Configuration Register
Similarly, make entry for Port-1 App Configuration Register by referring the pjt file attached.
Now, configure Transmit Source Capabilities
register (0x32) pointed by Virtual Address indexes. Virtual address 1 is the index
corresponding to 30W PDO.
Click Port-0 30W (0x1)
and then click Adjust Registers.
From the pop-up box, select
Transmit Source Capabilities (0x32) Register.
Click Transmit Source
Capabilities and make entry for 30W PDO as shown in Figure 2-11.
