asynchronous timing การใช้

They usually provide the interrupt handling required for any necessary asynchronous time-dependent hardware interface.
Asynchronous time-division multiplexing ( ATDM ), is an alternative nomenclature in which STDM designates synchronous time-division multiplexing, the older method that uses fixed time slots.
For a series of measurements on the same constant and asynchronous time interval one measures two different numbers of counted clock pulses n _ 1 and n _ 2 ( see picture ).
It is a specialized hardware-dependent computer program which is also operating system specific that enables another program, typically an operating system or applications software package or computer program running under the operating system kernel, to interact transparently with a hardware device, and usually provides the requisite interrupt handling necessary for any necessary asynchronous time-dependent hardware interfacing needs.
