Question

Which bit controls the external interrupts and the decrementer exceptions?

(a) FE1

(b) FE0

(c) EE

(d) ME

This question was addressed to me by my school principal while I was bunking the class.

I'd like to ask this question from RISC Exceptions-II in chapter Interrupts and Exceptions of Embedded Systems

Answer 1

Right choice is (c) EE

To explain I would say: The EE bit in the MSR controls the external interrupts and the decrementer exceptions.
