Abstract

A debug program is decoded in a command decoder to generate a debug start signal. Then, a signal processing operation is halted and a state of an internal circuit is latched and read to be supplied to an external circuit. When the reading of the state starts, a signal-processing continuation signal is generated, so that the signal processing operation is restored to be continued. Therefore, the debug program can be inserted to a program memory at plural addresses without braking the signal processing operation.
