你好！spi 从机接收程序，仿真调试时程序会跳出到 dbg_.h文件的void __DebugBreak(unsigned char operation, void *operands)程序，请问是什么原因？谢谢！
注：1、原例程增加一个数组，放在SPI数据接收程序，取消这个数组赋值这句时，程序是正常。
2、中断程序与void __DebugBreak如下。
unsigned char data[30];
#if defined(__TI_COMPILER_VERSION__) || defined(__IAR_SYSTEMS_ICC__)
#pragma vector=USCI_A0_VECTOR
__interrupt void USCI_A0_ISR(void)
#elif defined(__GNUC__)
void __attribute__ ((interrupt(USCI_A0_VECTOR))) USCI_A0_ISR (void)
#else
#error Compiler not supported!
#endif
{
while (!(UCA0IFG&UCTXIFG)); // USCI_A0 TX buffer ready?
UCA0TXBUF =UCA0RXBUF; // Echo received data
data[i] =UCA0RXBUF; //data[i] =UCA0RXBUF&0xff;
i++;
if(i==30)
{
i=29;
}
}
