19   *) Temperature Sensor (TS) - used to monitor core temperature (e.g. mr74137).
20   *) Voltage Monitor (VM) - used to monitor voltage levels (e.g. mr74138).
21   *) Process Detector (PD) - used to assess silicon speed (e.g. mr74139).
22   *) Delay Chain - ring oscillator connected to the PD, used to measure IO
25   *) Pre Scaler - provides divide-by-X scaling of input voltage, which can then
26      be presented for VM for measurement within its range (e.g. mr76006 -
27      divide by 2 pre-scaler).
