Really simple question from a hobbyist. Is it ok to let SDO (serial data out) and the clkout float on the PCF2129 RTC if I'm not using either, or should they be tied one way or the other? I'll be using I2C so don't need the SDO.
The SDO and CLKOUT pins of the PCF2129 device are output functions. It is okay to leave output pins floating.
Thanks so much for the quick reply. Really appreciate it.
