> Index of the vendor-neutral protocol and concept explainers, such as legacy terminology and I3C Common Command Codes, not tied to one Binho device.

This section is for vendor-neutral protocol and concept theory, such as "what is
I2C," "I3C vs I2C" and "SPI clock modes". It is not tied to a specific Binho
device or use case. It's distinct from the Hardware section (pure hardware/API
reference) and from [Application Notes](/guides/application-notes/)
(device-specific, task-oriented recipes).

* [**Dropping Legacy Terminology**](/guides/educational/dropping-legacy-terminology/)
* [**I3C Common Command Codes**](/guides/i3c/common-command-codes/)

This section is expected to grow with more protocol/interface education
content over time (I2C, I3C, SPI, UART, 1-Wire, GPIO, PWM), written as
vendor-neutral concept explainers.
