Power-On Reset and Brownout
Power supplies DVDD and DVDDIO each include a
brownout monitor that alerts the C through interrupt
when their corresponding supply voltages drop below
a selectable threshold. This condition is generally
referred to as brownout interrupt (BOI), and these
thresholds are set by the VDBI and VIOBI bits for DVDD
and DVDDIO, respectively. Continuous monitoring
ensures that a valid supply is present at all times while
the C is executing code. For example, the brownout
monitors check that DVDDIO does not drop during a
CAN bus transfer, or DVDD is not disrupted while the
C core is executing. The DVDDIO brownout monitor
also covers the analog peripherals if AVDD and DVDDIO
are directly connected.
The DVDD supply (internal core logic) also includes a
voltage supervisor that controls the C reset during
power-up (DVDD rising) and brownout (DVDD falling)
conditions (see Figure 5 for a POR and brownout timing
example).
