Would you like to send us a latest copy of SLUU337?
The default value for the CAPABILITY command in the UCD9222 is the same for all the existing UCD92xx controllers, 0xB0, which equates to the following:
The default value for the DEVICE_ID/ROM_VER for all released product can be found in the document Configuration Programming of UCD Devices which can be found under the Help --> Help & Documentation Center in the Fusion Digital Power Designer.
The UCD9222's DEVICE_ID/ROM_VER is:
The updated release of the SLUU337 document is passing through the technical documentation process and should be available in the next two to three weeks.
