This paper describes software development in particularly on microcontroller MCS51 family. Interrupt priority that available in this microcontroller are limited up to two level, first priority and second priority. Priorities on the same level may not interrupt each to another, but the higher level of priority should be serve above all the lower level by microcontroller immerdiately. In some cases we need more than two level of priority that can be reach only by software which need a deeper understanding on microcontroller imemdiately. In some cases we need a deeper understanding on microcontrolelr architecture. Especially, how the microcontroller fetching codes cycle, stacking program coutner during interrupt, and returning to previous program before the interrupt take place. No supporting devices are needed, an dno new architectural compiling are made. All purely by software, how to put acertain code in th eright place after interrupt take place including to control the interrupt mask too.
