If data is still attempted to write into the FIFO when the FIFO is already full, the overwritten event will occur.
= 0: The TJAT FIFO is not overwritten.
= 1: The TJAT FIFO is overwritten.
This bit is cleared to ‘0’ when it is read.
If data is still attempted to read from the FIFO when the FIFO is already empty, the under-run event will occur.
= 0: The TJAT FIFO is not under-run.
= 1: The TJAT FIFO is under-run.
This bit is cleared to ‘0’ when it is read.
These bits define a binary number. The (N1[7:0] + 1) is the divisor of the input reference clock, which is the ratio between the frequency of the
Writing to this register will reset the DPLL in the TJAT.
