RISC-V defines a software interrupt, a timer interrupt, and an external interrupt. Exceptions, which are synchronous. RISC-V defines exceptions to handle instruction, load, store, and AMO access faults; environment calls (used for system calls on Linux); illegal instructions; and breakpoints.
WebIf an ISR raises an exception it will not propagate to the main loop. The interrupt will be disabled unless the exception is handled by the ISR code. Interfacing to uasyncio¶ When an ISR runs it can preempt the uasyncio scheduler. If the ISR performs a uasyncio operation the scheduler’s operation can be disrupted. WebSep 3, 2011 · The difference between the two is that interrupts are used to handle external events (serial ports, keyboard) and exceptions are used to handle instruction faults, (division by zero, undefined opcode). Interrupts are handled by the processor after finishing the current instruction.
WebExceptions and Interrupts ¶ Ibex implements trap handling for interrupts and exceptions according to the RISC-V Privileged Specification, version 1.11. When entering an interrupt/exception handler, the core sets the mepc CSR to the current program counter and saves mstatus .MIE to mstatus .MPIE.
