Abstract
The circuit of the present invention provides a signal which allows data to be transferred between a first synchronous system to a second synchronous system. Where the first system is a Time-Division-Multiplexing (TDM) system and the second system is a Microprocessor system. The transfer is allowed after three or four memory cycles of the Microprocessor system after receiving the end of time slot signal. This invention requires that the Microprocessor system access the Time-Division-Multiplexed system as an Input/Output (I/O) device.
