5.1 Network Co-Processor (NCP) Application with UART Host
The BGM220S can be controlled over the UART interface as a peripheral to an external host processor. Typical power supply, pro-
gramming/debug interface, and host interface connections are shown in the figure below. For more details, refer to AN958: Debugging
and Programming Interfaces for Custom Designs.
