Supported trigger names: IRQ_RXIDLE, IRQ_TXIDLE, IRQ_BREAK
- IRQ_RXIDLE: The handler for IRQ_RXIDLE is called reliably 31 UART bit
times after the last incoming data.
- IRQ_TXIDLE: This IRQ is triggered after at least >5 characters are sent
at once. It is triggered when the TX FIFO falls below 4 elements. At
that time, up to 5 bytes may still be in the FIFO and output shift
register.
- IRQ_BREAK: The IRQ triggers if a BREAK state is detected at RX.
Properties & side effects:
- After a BREAK, a valid character must be received before another break
can be detected.
- Each break puts a 0xff character into the input buffer.
The irq.flags() value is cleared only with a new wanted event. Do not
change the flags otherwise.
