/*
** Extended Interrupt Registers
** These registers are used as follows:
** 1. The mask register is used to allow peripheral function and external
**    interrupts to function. To enable an interrupt, set the appropriate
**    bit.
** 2. The status register contains the state of the peripheral functions
**    and external devices. This register should be read to poll devices
**    such as the uart when the interrupts are not enabled. Writing to this
**    register will clear the interrupt.
** 3. The Cause register is similar to the status register, with the
**    exception that it only shows the bits that are set in the mask
**    register. This register should be read to determine which interrupt(s)
**    need to be serviced. This register when written to will CAUSE the interrupt.
