大家好：
我想使用GPIO输出XBAR来控制外部中断信号产生，使用如下程序，发现中断并不响应，需要如何配置呢
//
// Included Files

#include "driverlib.h"
#include "device.h"
__interrupt void Xint1ISR(void)
{
Interrupt_clearACKGroup(INTERRUPT_ACK_GROUP1);
}
//
// Main
//
void main(void)
{
//
// Initialize device clock and peripherals
//
Device_init();
//
// Assign RAMs and Flash banks to CPU2.
// In the default CPU2 linker cmd files, GS4, FLASH_BANK3 and FLASH_BANK4
// are used for allocating various CPU2 sections.
// In case CPU2 needs additional RAM or Flash regions, CPU1 needs to assign
// its ownership to CPU2 using the following functions :
// - MemCfg_setGSRAMControllerSel for GSRAM
// - SysCtl_allocateDxRAM for DRAM
// - SysCtl_allocateFlashBank for Flash
//
MemCfg_setGSRAMControllerSel(MEMCFG_SECT_GS4, MEMCFG_GSRAMCONTROLLER_CPU2);
SysCtl_allocateFlashBank(SYSCTL_FLASH_BANK3, SYSCTL_CPUSEL_CPU2);
SysCtl_allocateFlashBank(SYSCTL_FLASH_BANK4, SYSCTL_CPUSEL_CPU2);
//
// Boot CPU2 core
//
#ifdef _FLASH
Device_bootCPU2(BOOTMODE_BOOT_TO_FLASH_BANK3_SECTOR0);
#else
Device_bootCPU2(BOOTMODE_BOOT_TO_M0RAM);
#endif
//
// Initialize PIE and clear PIE registers. Disables CPU interrupts.
//
Interrupt_initModule();
//
// Initialize the PIE vector table with pointers to the shell Interrupt
// Service Routines (ISR).
//
Interrupt_initVectorTable();
GPIO_setPadConfig(201U, GPIO_PIN_TYPE_STD);
GPIO_setDirectionMode(201U, GPIO_DIR_MODE_OUT);
GPIO_setPinConfig(GPIO_201_OUTPUTXBAR1);
XBAR_setOutputMuxConfig(OUTPUTXBAR_BASE,XBAR_OUTPUT1,XBAR_OUT_MUX07_INPUTXBAR4);
GPIO_setInterruptType(GPIO_INT_XINT1, GPIO_INT_TYPE_RISING_EDGE);
GPIO_enableInterrupt(GPIO_INT_XINT1);
GPIO_enableInterrupt(GPIO_INT_XINT1);
Interrupt_enable(INT_XINT1);
Interrupt_register(INT_XINT1, &Xint1ISR);
//
// Enable Global Interrupt (INTM) and realtime interrupt (DBGM)
//
EINT;
ERTM;
//
// Loop Forever
//
for(;;)
{
GPIO_writePin(201U, 0);
//
// Delay for a bit.
//
DEVICE_DELAY_US(500000);
GPIO_writePin(201U, 1);
//
// Delay for a bit.
//
DEVICE_DELAY_US(500000);
}
}
