The function of the above three sets of registers are the same. However, they correspond to different THDLC.
These 2 bits set the lower threshold of the FIFO. If the fill level is below the lower threshold, an interrupt may be generated.
= 00: 16 bytes
= 01: 32 bytes
= 10: 64 bytes
= 11: 96 bytes
These 2 bits set the upper threshold of the FIFO. Once the fill level exceeds the upper threshold, the data stored in the FIFO will start to be trans-
= 00: 16 bytes
= 01: 32 bytes
= 10: 64 bytes
= 11: 128 bytes
