5 RS9116 CC0 Module Reference Schematics, BOM and Layout Guidelines
1. Customers should include provision for programming or updating the firmware at manufacturing.
2. If using UART, we recommend bringing out the SPI lines to test points, so designers could use the faster interface for progra mming the firmware as needed.
3. If using SPI as host interface, then firmware programming or update can be done through the host MCU, or if designer prefers to program standalone at
manufacturing, then it is recommended to have test points on the SPI signals.
4. If SDIO/SPI/UART interface is not used, then their respective IO domains must still be connected to the power supply.
