Abstract
A method to detect when a bus master device terminates a bus data transfer operation includes providing a first counter clocked by a first clock signal and providing a second counter clocked by a second clock signal. Outputs of the first and second counters are compared, and it is determined if termination of the bus transfer operation has occurred based on comparing the outputs.
Claims13
A method of detecting termination of a bus transfer operation, comprising:
- providing a first counter clocked by a first clock signal;
- providing a second counter clocked by a second clock signal;
- comparing outputs of the first and second counters;
- and
- determining if termination of the bus transfer operation has occurred based on comparing the outputs.

A method of detecting when a bus master device terminates a bus data transfer operation, comprising:
- using a first counter clocked by a first clock signal to cyclically generate a predetermined sequence of output signals;
- using a second counter clocked by a second clock signal to cyclically generate the predetermined sequence of output signals;
- and
- detecting a mismatch between an output signal from the second counter with a corresponding output signal from the first counter.
