3.10. UART Interfaces
The module provides the following four UART interfaces:
 UART5: 4-wire UART interface, hardware flow control supported.
 UART6: 4-wire UART interface, hardware flow control supported, multiplexed from SPI interface.
 UART2: 2-wire UART interface, used for debugging.
 UART4: 2-wire UART interface.
The following table shows the pin definition of UART interfaces.
