Abstract
The present invention provides a signal processing apparatus having at least a boundary scan chain for carrying out a boundary scan test, a CPU capable of being controlled by the boundary scan chain, a non-volatile memory for storing an operating program of the CPU and necessary data, and an input terminal for inputting data and other control signals from the outside to the boundary scan chain, a register for holding data transferred from the boundary scan chain and a memory for holding the data read from the register. During data rewriting, based on the control of the boundary scan chain, a rewriting program is input via the input terminal from a writing device to the boundary scan chain and then stored in the memory through the register, the CPU inputs rewriting data to write it into the non-volatile memory based on the control of the rewriting program stored in the memory.
