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.-This software shows the necessary configuration to use External Interrupt 0
