Hi Tomas,

I had an old datasheet (should have checked) from when the PCF2129 and PCF2129A had different datasheets, and here the datasheet for the PCF2129A version did not contain this parameter. I have now updated to the latest datasheet which covers both variants and includes this parameter.

Hi Thomas,

It is 0.2 x Vdd as shown in the PCF2129 datasheet:
