my corporation has bought a group of nRF2401 card,which were controlled by MSP430F2001.but the security fuse has broken.i want to write the receiving code,but i didn't know the configuration word of the nrf2401,how can i do to read the correct configuration word?

I'm pretty sure that you can't read configuration data out of the nRF2401 (if you had an nRF24L01, you could, though). I'm not totally sure by how you wrote your post, but if the microcontrollers still work then you can read the data that is coming out of the SPI port on startup that goes to the 2401 (this would be the configuration bits). The easiest way to do this is with an oscilloscope or a logic analyzer if you have access to one. You should definitely read up on the 2401 in its datasheet so that you know what kind of information to expect.
