View Ref-FileStatus Register (SR)

    This 16-bit SR consists of a mode register (MR) in the high-order
eight bits and a condition code register (CCR) in the low-order eight
bits. The SR is stacked when program looping is initialized, when a
JSR is performed, or when interrupts occur, (except for no-overhead
fast interrupts).
