System Control
Register 3: Brown-Out Reset Control (PBORCTL), offset 0x030
This register is responsible for controlling reset conditions after initial power-on reset.
Note: The BOR voltage values and center points are based on simulation only. These values are
yet to be characterized and are subject to change.

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
VDD under BOR0 Event Action
The VDD BOR0 trip value is 3.02V +/- 90mv.
Value Description
0 A BOR0 event causes an interrupt to be generated in the
interrupt controller.
1 A BOR0 event causes a reset of the microcontroller.

VDD under BOR1 Event Action
The VDD BOR1 trip value is 2.88V +/- 90mv.
Value Description
0 A BOR1 event causes an interrupt to be generated to the
interrupt controller.
1 A BOR1 event causes a reset of the microcontroller.
