These 4 digital outputs are open drain outputs and they are driven by GPIO-11, GPIO-16, GPIO-17
and GPIO-22 in Raspberry Pi Compute Module 4 (please see table below).

Remarks
: every time you change the output value, you need to give a rising edge on bit-2 in the
register in I2C-6 (address=0x20).
Each output can bear up to 30V DC and can drain up to 500mA current. Below is an example to drive
a load with digital output.
