我说错了，今天看了keil关于C8051F340的仿真说明，是因为KEIL不完全支持340软件仿真所致。

NOTE：
Simulation for this device is provided by the default peripheral simulation driver.Complete peripheral simulation is not available at this time.
The following on-chip peripherals are not simulated.
Crossbar
External & On-Chip memory
Interrupts (Including External)
Port 0
Port 1
Port 2
Port 3
Power Saving Modes (Idle and Power Down)
Serial UART 0 (Enhanced Interface)
Timer 0
Timer 1
Timer 2
上述外设keil都不支持软件仿真。
