The [chip.<chip_name>] section allows you to configure chip-specific settings for different microcontrollers. These settings are optional and only needed when you want to override the default behavior.
The nRF52840 has two DC/DC regulators that can improve power efficiency when enabled with proper hardware support.
Do not enable DC/DC regulators without an external LC filter being connected, as this will inhibit device operation, including debug access, until an LC filter is connected.
The nRF52833 has one DC/DC regulator available for configuration.
Do not enable DC/DC regulator without an external LC filter being connected, as this will inhibit device operation, including debug access, until an LC filter is connected.
