A subroutine is an instruction that performs a certain function. It must be called by the main program (or subroutine) to execute. It cannot interrupt the execution order of other instructions. When multiple subroutines coexist, they are executed in the order in which they are called.
The interrupt program is an interrupt source interrupt, and an interrupt request is issued to the CPU. After being allowed, the CPU suspends the executing program, responds to the interrupt to do, returns after completion, and the CPU continues to execute the following command from the interrupted instruction. When multiple interrupt sources issue interrupt requests at the same time, the priority of each interrupt must be specified. The higher priority is executed first and does not need to be called by other programs.
Electronic Components Transformer
Transformer is a device that USES the principle of electromagnetic induction to change the ac voltage. Its main components are primary coil, secondary coil and iron core.The main functions are: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization (magnetic saturation transformer), etc.According to use can be divided into: power transformer and special transformer (electric furnace change, rectifier, power frequency transformer, voltage regulator, mining, audio transformers, intermediate frequency transformer, high frequency transformer, impact transformer, instrument transformer, electronic transformer, reactor, transformer, etc.).The circuit symbol T is often used as the beginning of the number. Examples: T01, T201, etc.
