我用的芯片是5402
程序可以下载和运行,但是每次只要涉及到端口的指令就执行不了,比如用PORTW,PORTR给I/O空间送数据或读取数据时,会有出错信息:
can't single step target program:
Error 0x80000020/-1058
Fatal Error during:Execution,
Device driver: Emulator Controller not responding
It is recommended to RESET EMULATOR . This will disconnect each target from the emulator. ...
Trouble Reading Target CPU memory: Cannot access memory
address 0xFA.
接下来连程序下载也不行了.提示下载失败:
