#156616 - I do not understand your question; however ... Responding to: ???'s previous message |
want to know how the UART pins TXD and RXD are terminated inside the MCU
TXD and RXD are in a traditional '51 also known as p3.0 and p3.1 I do not understand your question (wh7y do you ask); however, there is no difference, whatsoever, between p3.0 and p2.5, regular quasi=bidirectional pins Erik |
