Serial port D pins are allocated as shown:

By default, Serial D signals are configured to their respective GPIO signals.

It is the responsibility of the driver to configure them properly.

Serial port A TTL

interface The serial (UART) port A interface is a TTL interface connected to a 2x5 pin, 0.1”

connector, X4. The connector supports only TTL level.

The serial port A interface corresponds to NS9215 UART port A.

Serial port A pins are allocated as shown:

By default, Serial A signals are configured to their respective GPIO signals. It is the

responsibility of the driver to configure them properly.

Serial Port A must not be connected if SPI or WakeUp functionality is used.
