These bits represent a 2’s complement signed integer. If the value is multiplied by the value in the
FREQ_MON_FACTOR[3:0] bits (b3~0, 2EH), the frequency of an input clock with respect to the reference clock in ppm will
be gotten. The input clock is selected by the IN_FREQ_READ_CH[3:0] bits (b3~0, 41H).
The value in these bits is updated every 16 seconds, starting when an input clock is selected.
