<p>PURPOSE:To easily perform debugging such as the setting of mode and setting of port for input/output data at the digital signal processor which disables confirmation at ICE in the case of software development. CONSTITUTION:This device is provided with a code conversion circuit 10 for outputting a code 16 expressing a register required for debugging, R/W signal control part 9 for outputting an R/W signal 17 for debugging data, and data latch part 8 for holding data for debugging, and desired debugging data 18 to be confirmed are selected from the debugging code 16 outputted from the code conversion circuit 10 and the debugging data R/W signal 17 outputted from the R/W signal control part 9. By verifying these data, a program for test is unnecessitated, and debugging is facilitated.</p> |
