Micro-controller capable of extending memory bank includes a microprocessor, multiple memory banks, a circuit of controlling memory banks and a multiplexer. Capacity of the multiple memory banks is larger than addressable space of single command of the microprocessor. Interrupt service routine (TSR) is stored by some of memory banks. The circuit of controlling memory banks generates a selection signal based on interruption occurrence of microprocessor and end signal of executing TSR. The multiplexer includes a first input end, second input end, a selecting end and an output end. Page selection signal, which is received by first input end and is sent by microprocessor, is output base on the selection signal input from input end of the circuit of controlling memory banks, or preconcerted page selection signal received by second input end. Thus, when interrupt happens, the microprocessor is able to access data from the memory bank, which stores the TSR.

The invention relates to a technique for manufacturing a manganese alloy, in particular to a process for solidifying, granulating and forming a manganese metal or a manganese alloy, which solves the problems that in the prior art for manufacturing and casting the manganese alloy, granules are irregular and the dust index is high when a manganese alloy nail is broken. The process comprises the steps of melting raw materials, moulding the molten metal and stirring the molten metal through an electromagnetic field before moulding. In the process of stirring in the electromagnetic field; and under the condition of casting temperature, magnetic force makes the solidifying molten metal generate vortex motions or makes the flow of the molten metal at least generate turbulence effect, and a dendritic crystal is broken to obtain a beneficial crystalline structure. The prior art can generate 15 percent of the dust index in the production process and consumes energy in recycling. The product obtained ...
