The function of the above three sets of registers are the same. However, they correspond to different THDLC.
= 0: The FIFO is not full.
= 1: The FIFO is full of 128 bytes.
= 0: The FIFO is not empty.
= 1: The FIFO is empty.
= 0: The fill level of the FIFO is not below the lower threshold set by the LL[1:0] bits (b3~2, E1-0AAH / 0AB / 0ACH).
= 1: The fill level of the FIFO is below the lower threshold set by the LL[1:0] bits (b3~2, E1-0AAH / 0ABH / 0ACH).
