PRODUCTION DATA.
The VDD supply has two monitors:
The POK monitor is used to keep the digital circuitry in reset until the VDD power supply reaches an acceptable operational level. The digital reset is only released when the POR has deasserted and the POK monitor for each supply indicates that power levels are in operational ranges. The BOR monitor is used to generate a reset to the device or assert an interrupt if the VDD supply drops below its operational range.
NOTE
VDDA BOR and VDD BOR events are a combined BOR to the system logic, such that if either BOR event occurs, the following bits are affected:
In addition, the following bits control both BOR events:
See the System Control chapter of the MSP432E4 SimpleLink™ Microcontrollers Technical Reference Manual for more information on how to configure these registers.
Figure 5-3 shows the relationship between VDD, POK, POR, and a BOR event.
