| JoeP:
I'm running out of pins on a microcontroller and need a way to turn off all its output pins from a single input pin. Could I use Vdd as this pin? Is there a reason why I shouldn't do this, and are there any issues this could cause? It would happen very infrequently, but for long periods of time. Would it damage the chip or will it be fine? Thanks, Joe |

why not use the reset pin? |
| JoeP:
I don't know whether mine's got one? The datasheet is here: http://www.farnell.com/datasheets/2137994.pdf?_ga=2.11177268.1643568016.1539016190-2008006305.1520009189 It says nothing about a reset pin though. |
| Rerouter:
RA3, MCLR for pics, pulling him low resets the device unless you have set the fuses to use it as an input. |
| JoeP:
Aah, ok. Unfortunately I'm using it as an input. |
