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 5, 2024 · The use of asserts is one of the best ways to find bugs, unintended behavior, programmatic errors, and to catch when systems are no longer 100% functional and need to be reset to recover.
