Supported for all SAMD51 devices and SAMD21 with external flash. For interrupt events, IRQ_RX and IRQ_TXIDLE are provided. IRQ_RX is called for every received byte. This may not be useful for high data rates, but can be used to build a wrapper class providing an IRQ_RXIDLE event or to signal just the first byte of a message. IRQ_TXIDLE is called only when messages are longer than 5 bytes and triggers when still 5 bytes are due to be sent. The SAMD hardware does not support implementing IRQ_RXIDLE.
