A drop-down menu selection at the top right of the register map indicates how the registers are written as the
user interacts with the register page. With
Immediate
selected, any update to the register page is automatically
sent to the PMIC, whereas
Deferred
will wait for the
Write Register
or
Write All Registers
instructions before
communicating with the device. After each write, the register page will automatically read the affected register
address to confirm the latest value in the device.
6.2.4 Device Configuration
The Device Configuration section is organized into selectable tabs at the top of the page, where only the
contents of the blue tab is actively displayed. Each tab contains categorized visual instruments relating to
individual bit fields within the register map. Each instrument is linked to the latest bit values in the register map
table, and can be used to alter settings within the PMIC through the dropdown menus or check box features. If
the
Auto Read
function in the register map is inactive, the
Read All Registers
button in the top right area of the
Device Configuration page can be used to manually refresh the register page, which will then update the
instruments with the latest device values.
The PMIC incorporates
Control Lock
and
Configuration Lock
features that can prevent I
2
C writes to various
registers within the device. The status of these locks will always be displayed in the top right hand corner of the
Device Configurations page, and can be toggled by clicking their associated checkbox. When the GUI is properly
connected to the EVM and write instructions appear to be ignored by the PMIC, confirm the status of these
indicators to verify the device is able to accept new write instructions.

6.2.4.1 Using Device Configuration to Define Spin Settings
In some circumstances, TI may provide customized, pre-programmed devices for the camera application.
Contact a local TI sales representative for more information.
The Device Configuration tabs in the GUI can be used to define custom settings for TI to pre-program into the
device Non-Volatile Memory (NVM). Before beginning the spin definition, see the
to determine if there is an exisiting spin that is already compatible with the target application and the
image sensor or both.
Since the visual instruments in the Device Configuration page link directly to the corresponding bits and registers
in the Register Map page, the Device Configuration page can be used to quickly define desired OTP register
settings.
