关于Energia MSP432P401r的外部中断



Energia  MSP432P401r的外部中断有几个?

我想用它做8路计数,可行不?

  • 手册里写道:

    The Cortex-M4 processor on MSP432P401x MCUs implements an NVIC with 64 external interrupt lines
    and 8 levels of priority. From an application perspective, the interrupt sources at the device level are
    divided into two classes, the NMI and the User Interrupts. Internally, the CPU exception model handles the
    various exceptions (internal and external events including CPU instruction, memory, and bus fault
    conditions) in a fixed and configurable order of priority. For details on the handling of various exception
    priorities (including CPU reset and fault models), see the ARM-V7M architecture reference manual at
