In the datasheet of the PIC I am using it says
"Each of the PORTB pins has a weak internal pull-up"
What does this mean and imply??
"Each of the PORTB pins has a weak internal pull-up"
What does this mean and imply??
so I dont need to put my own pull up (or down) resistors when I am not using the pins???It means PORTB pins have internal pull up resistors.
Yes. Some newer mcus allow both (internal) pull-up and pull-down.Is it possible to "pull up" and "pull down" at the same time???
So to detect if a device is attached to that pin. Some chips, like linear's oscillators, use that approach to program the frequency output.How can this be possible? I am not sure but I think they are input pins btw...
Yes, apparently I can do that with OSC2 since this can act as RA5 too, but what about OSC1. This can not be set as an output....therefore what to do?Microchip suggests setting all unused pins as outputs and setting their level to zero.
What chip? Usually there are configuration bits to set both to outputs if the internal oscillator block is used.Yes, apparently I can do that with OSC2 since this can act as RA5 too, but what about OSC1. This can not be set as an output....therefore what to do?
I have never seen a Microchip device where that is true. Check the data sheet again.Yes, apparently I can do that with OSC2 since this can act as RA5 too, but what about OSC1. This can not be set as an output....therefore what to do?
Read the device datasheet.therefore what to do?
