(Refer to the description of the JIT_NL register.)
These bits, together with the JIT_N[11:8] bits, reflect the greatest negative peak value of the demodulated jitter signal which is
measured by channel 0. They are updated automatically or manually, as determined by the JM_MD bit (b1, JM). They should be
read in the next round of jitter measurement; otherwise, they will be overwritten.
The relationship between the greatest negative peak value and the indication in these bits is:
Negative Peak = [JIT_NH, JIT_NL] / 16 (UIpp)
