SPI interface
The development board provides access to the SPI interface on the module using
the SPI connector, X8. The SPI interface on the development board is shared with
UART_A (NS9215 port A). Because the module’s SPI interface is shared with a UART
interface, you cannot use both simultaneously.
Note: The default configuration of UART port A is to support GPIOs. To move from
GPIO to UART or SPI, you need to configure the software properly.
