Resistive Pull Up
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
