SLAU888 may 2023 AFE882H1
To use an external SPI or UART controller with the EVM board, disconnect the connections from the FTDI controller to the devices at the level shifters. To disable the level shifters, use the J25 header and add jumpers from SPI_EN, UART_EN, and RESET_EN to ground. After the level shifters are disabled, connect an external controller to pin headers at J9, J15, and J16 to control the AFE882H1 and XTR305.
