    Resistive Pull Up

      Hi,

         

      How  much is the resistance of the internall pull-up of a PSoC5LP?.

         

      Currently I have a PSoC5LP connected to 20 SPI Slave devices with 20 separate chip select lines (digital output, resistive pull up).

         

      Since the pins are connected to Vdd, I would like to know how nuch is the current draws, and if I need an external pullup resistor
