Note: Bits in this information register cannot cause an interrupt to occur.
Bits 0 to 3: Transmit FIFO Level (TFL[3:0]). These real-time status bits indicate the current depth of the transmit
FIFO in 16-byte increments.
Bit 4: Transmit FIFO Empty (TEMPTY). This real-time status bit is set when the transmit FIFO is empty and
cleared when the transmit FIFO contains one or more bytes.
Bit 5: Receive FIFO Empty (REMPTY). This real-time status bit is set when the receive FIFO is empty and cleared
when the receive FIFO contains one or more bytes.
