"While using the MKE02Z64 microprocessor to implement serial port data transmission and reception based on the FRDM-KEXX-Driver-Library-Package routine, I observed that the received data consistently omitted the second byte. For instance, when I transmitted 7E 02 30 32 0D (in HEX) from a PC, the simulated microprocessor consistently received 7E 30 32 0D. Furthermore, for other commands, there was always a missing second byte. Despite thorough investigation, I have been unable to identify the root cause of this issue."
