The main goal of the TX interrupt (really an END OF TX) is to send the content of a buffer (multiple bytes) automatically. When implemented in a proper way: Enable the TX interrupt. The user code starts transmission by sending only the first byte in the buffer. At the end of TX (of the first byte), an interrupt will be generated.

WebNov 10, 2014 · With an interrupt the current state (or context) is stored in a temporary area (usually, but not always, the stack). The ISR then does its thing, and the state is then restored and the interrupt routine returns. The crucial thing here is that the ISR returns exactly where it left off in the same thread. A context switch looks just like an ... WebFeb 24, 2015 · 7.
