49.4.13.2 Single threshold noise modes
These modes reset by MODE[3:2]=01 and 10. The difference between these two modes
is that in mode 2 (MODE[3:2]=10) there is a frequency limitation circuit that enables the
circuit to operate in higher frequencies. In mode 1 (MODE[3:2]=01) this frequency
limitation circuit is not enabled.
In this mode the thresholds are set by user via register bits as described in the following
table.
During these modes the internal oscillator rails are set to the maximum (equivalent to
DVOLT[1:0]=00).
