Reserved. Unknown During Read.
Global interrupt bit. This bit is set whenever the MACint
signal to the interrupt controller is active. Writing a one to
this bit location will clear this bit until a new interrupt
condition occurs.
Reserved. Unknown During Read.
Global interrupt mask bit. When set, any interrupt enabled
by the Interrupt Enable Register will set the Global
Interrupt Status interrupt bit. When clear, no interrupts will
reach the processor.
