4.8.1 Compensation Network
A voltage regulator needs feedback from the VCORE voltage to be able to adjust (control) output voltage. For this reason, two bridges are
implemented in the external MC34FS6407 or MC34FS6408 circuitry. Static feedback (steady-state) voltage is defined by a simple resistor
bridge (given by RA3/RB3 and RA4). Dynamic behavior of the regulator is controlled by another bridge that is an RC divider (defined by
RBx, CBx, R1, C1, R2, C2). Figure 4 shows the compensation network. Steady-state voltage can be either 1.2 V or 3.3 V. To tune the
dynamic performance, the board is equipped with two different bridges (possible combinations of the jumpers J1 and J9 are shown in
Table 7). The combinations shown in Table 7 are chosen to provide optimal performance for the given output voltage. The real dynamic
performance can differ for different applications and can be tuned by changing the compensation network and by adding output capacitors
(J2).

4.8.2 Second Resistor Bridge - VDRIFT Monitoring
To increase the safety level of an application, a second resistor bridge has been added. This bridge generates the same voltage as the
bridge connected to FB_core pin. If the difference between voltages is greater than VDRIFT , the FS state machine is impacted.
Invoking this functionality involves both the board hardware and the software configuration. On the hardware side, the second resistor
bridge must be configured by jumper J18, as shown in the Figure 5, and adjusted by the potentiometer R17 to set the same voltage as on
the first bridge. Software sets registers INIT_Vreg1 (bit Vcore_FB to 1) and register INIT_FSSM1 (bit IO_1_FS to 1).
