说明：  C8051F020单片机中断程序 This software shows the necessary configuration to use External Interrupt 0 (/INT0) or External Interrupt 1 (/INT1) as an interrupt source. The code executes the initialization routines and then spins in an infinite while() loop. If the button P3.7 (on the target board) is pressed, then the edge-triggered /INT0 input on P0.0 will cause an interrupt and toggle the LED.
