... Interfacing to microprocessors with bidirectional reset pins Microprocessors with bidirectional reset pins can contend with the STM6321 / 6322 / 6821 / 6822 / 6823 / 6824 / 6825 reset output. For example, if the reset output is driven high and the microprocessor wants to pull it low, signal contention will result. To prevent this from occurring, connect a 4.7 kΩ ...
