2.2.3.2 External SPI and UART Controllers

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 J19 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 J6 and J12 to control the AFE881H1.
