It will not be detected, generally speaking, unless the MCU code "looks" at it. Normally, the pin, on P1, P2, or P3, would have to be written to with a '1' before it is read. That provides a weak pullup and subsequently reflects the logical state of the pin when it is read by the MCU.
You could learn a great deal more about this by (1) reading the device-specific datasheet, and (2) by searching this website. Had you read the instructions on posting before you posted, you'd have known that query titles like yours are not very useful. You should be more specific ... and you should search on the specifics BEFORE POSTING! RE |
