Function (RX Mode)
Pin IRQ is set to “1” if 4 received bytes are in the TX/RX data buffer or a receiving error
occurred
Pin IRQ is set to “1” if 8 received bytes are in the TX/RX data buffer or a receiving error
occurred
Pin IRQ is set to “1” if 12 received bytes are in the TX/RX data buffer or a receiving error
occurred (default)
Pin IRQ is set to “1” if a receiving error occurred
Function (TX Mode)
Pin IRQ is set to “1” if 4 bytes remain in the TX/RX data buffer or the TX data buffer is empty
