Web13 mrt. 2024 · Is there any way to add a weak pull-down resistor for used input I/O pins? Also, there is an optional bus-hold feature. Can I define an inout port and have an initial output value, then change to input mode to let the input hold the value of the initial output? In this case, how high a voltage from the pin can stop holding the value? Web23 sep. 2024 · Solution To calculate the internal pull-up or pull-down you will need Irpu (max) or Irpd (max) from the device DC and AC Switching Characteristics Datasheet. This Irpu / Irpd value is based on the Vcco voltage. With this information you can calculate Rpu and Rpd using the equations below. Rpu = Vcco / Irpu Rpd = Vcco / Irpd For example: WebWago pop popcorn in brown bag
