psoc5lp上拉电阻是多少？

你好，
实验的一个psoc5lp上拉电阻是多少？.
目前我有一个psoc5lp连接20个SPI从设备与20个独立的片选线（数字输出电阻上拉）。
由于引脚连接到Vdd，我想知道多少是目前的画，如果我需要外部上拉电阻

  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
