Abstract

The embedded micro-controller unit includes a serial interface according to the present invention. A program control device connects the embedded micro-controller unit. The serial interface will send a request signal to a micro-processor while renewing program codes. The micro-processor will transfer the power of controlling program memory to the serial interface and then go into idle state or halt state after receiving the request signal. The program control device may directly write new program codes into the program memory through the serial interface.
