The issue here is not the UART, but the amount of overhead in the ISR If yoou ISR takes longer than it takes the UART to fetch the next byte, you WILL be lost. I'd say, rather, if the byte _processing_ takes more than the next byte receiving, a byte will be lost. It is not always necessary to use interrupts. Depends on application of course. JW |
