资 源 简 介
The ADAU1701/ADAU1702 can be used in a system without a microcontroller by using the self-boot feature. This allows the ADAU1701/ADAU1702 to boot itself as an I2C master from an external EEPROM at power-up or reset. In the absence of a micro-controller, real-TIme control of the DSP is achieved by using the mulTIpurpose pins with buttons, switches, potenTIometers, or other control devices. When designing a self-booTIng system with these ICs, some consideration must be taken for in-system programming and tuning from the SigmaStudio™ graphical programming tool.
