Board Interrupt Configuration Register (BICFG)

The Board Interrupt Configuration Register holds a series of bits defining the interrupt routing
for the Watchdog. If the Watchdog timer fails, it can generate an IRQ5 interrupt.
The enumeration signal is generated by a hot swap compatible board after insertion and prior
to removal. The system uses this interrupt signal to force software to configure the new board.
The derate signal indicates that the power supply is beginning to derate its power output.
