| Zusammenfassung: | A method and apparatus for digital I/O expander chip with multi-function timer cells have been disclosed. A series of match reload registers load a series of match registers which are driven by a master counter. The status of the match registers can be retrieved through ports. The master counter is reloaded on rollover by a count limit register. The master counter has increment/decrement control and the rollover can be used in an interrupt control block to generate an interrupt request. |
