The following figure shows a reference design of the main UART interface:
Figure 18: Main UART Reference Design (Translator Chip)
Another example with transistor translation circuit is shown as below. For the design of circuits in dotted
lines, please refer to that of circuits in solid lines, but please pay attention to the direction of connection.
