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, T1/J1-0AAH,... / 0ABH,... / 0ACH,...).
= 1: The fill level of the FIFO is below the lower threshold set by the LL[1:0] bits (b3~2, T1/J1-0AAH,... / 0ABH,... / 0ACH,...).
