Reserved
Interrupt source (INT_SRC): Interrupts are prioritized into three levels, as shown
below:
Interrupt (INT): When cleared, indicates an interrupt is pending.
 00: Not used
 01: THRE is source of interrupt
 10: DR is source of interrupt
 11: Line Status is source of interrupt, OE, PE, or FE.
