PCA9536: p-port I/O

Part Number: PCA9536


P0-3 has an internal pull-up resistor of 100 kΩ.

P0-3 goes High at startup.(Before register setting)

I want to set the P0-3 output to Low at startup using pull-down resistor.

What is the minimum value of the pull-down resistor?

I want to reduce current consumption.

Best regards,
