#183509 - how to use bit 9 for data bytes? Responding to: ???'s previous message |
bit 9 is what distingguishes data bytes from "control" bytes:
bit 9 SET identifies a byte as a "control" byte; bit 9 CLEAR identifies a byte as a data byte. Erik's suggestion was that you have a "control" byte at both the start and the end of a message: http://www.8052.com/forum/read/183505 |
