The E3900 and A3900 Series Processors support four LPSS_UART ports, while the N- and J- Series Processors support only LPSS_UART [2:1] ports. 2. The LPSS_UART1 port is dedicated for discrete Global Navigation Satellite System (GNSS). This port can be used for generic UART functionality if GNSS is not used. 3. The LPSS_UART2 port is dedicated for host OS debug. 4. The LPSS_UART0 and LPSS_UART3 ports are for generic UART functionality. 5. Only UART [1:0] ports support DMA.
