2.0 APPLICATION INFORMATION
2.1 OPERATION WITH EXTERNAL MCU
Stereo module support UART command set to make an external MCU to control module.
Here is the connection interface between BMXX and MCU.
FIGURE 2-1: INTERFACE BETWEEN MCU AND BMXX MODULE
MCU can control module by UART interface and wakeup module by PWR pin. Stereo module
provide wakeup MCU function by connect to P0_0 pin of module.
“UART Command Set” document provide all function which module support and UI tool will help
you to set up your system support UART command.
For more detail description, please reference “UART_CommandSet_v154” document and
“IS20XXS_UI” tool.
