<P>PROBLEM TO BE SOLVED: To provide a data processing apparatus which is capable of surely reporting occurrence of an error without increasing the number of output terminals and test patterns and a test time. <P>SOLUTION: The data processing apparatus includes a memory, an error detection circuit, a timing adjustment circuit, and a terminal. The error detection circuit detects an error on the basis of an output of the memory to output an error detection signal. The timing adjustment circuit makes a pulse width of the first pulse signal after the start of a prescribed operation out of pulse signals included in the error detection signal, longer than a pulse width output from the error detection circuit. The terminal outputs an output of the timing adjustment circuit to the outside when testing the memory. <P>COPYRIGHT: (C)2010,JPO&INPIT |
