3.10. UART Interfaces
The module provides the following four UART interfaces:
⚫
UART5: 4-wire UART interface, hardware flow control supported, 1.8V power domain
⚫
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.
