.4. Application Programming Interface (API)
An application programming interface (API) which the host MCU will communicate with is embedded inside the
device. The API is divided into two sections, commands and properties. The commands are used to control the
chip and retrieve its status. The properties are general configurations which will change infrequently. The available
commands are shown in Table 10.
