Description

PLIC Interrupt Controller

Base riscv.ovpworld.org PLIC model plus these Andes extension features:

- Software-programmable interrupt generation (writable pending registers)

- Configurable interrupt trigger types

- Preemptive priority interrupts

Limitations

NOTE: The following Andes PLIC extension features are not supported:

- Vectored interrupt extension is not implemented
