PRIORITY and THRESHOLD

[spzeno]

The datasheet's section 4.3.1 says that

I wonder that if both PRIORITY and THRESHOLD is 0, whether the interrupt will be masked?

A priority of '0' means the interrupt is never generated. The PLIC spec says: "The priority value 0 is reserved to mean “never interrupt”, and interrupt priority increases with increasing integer values."
