Abstract

In embedded system design using a microprocessor, one of the problems encountered by the designer is the limited number of input ports. This limitation restricts the number of input keys that can be implemented in a product. These papers describe an alternative solution to sense a number of input keys by using the input capture function of a microprocessor.
