I have connected a microcontroller GPIO pin, which is intended to be an output, to a DC-DC converter's active high Enable
input pin. Since this pin is active high, and because I do not want this converter to be ON at power up or before it is required, I have used a pull-down resistor on this line to keep it disabled.
I am slightly confused as to where should this pull down resistor be ideally placed. Should it be placed near the GPIO pin or the Enable
pin?
Same question for pull-up resistor, in the case when Enable
is active low and I have to use a pull up on the line.
