I'm working with a single PCF8576C and I'm not sure where to connect the CLK and SYNC pin in static mode.
The datasheet says that those pins should be at a defined level(Vss or Vdd).
I'm using the internal oscillator of the PCF8576C that means I get an output clock signal from CLK for cascaded PCF8576. Can I simply pull both pins up ?
Thanks in advance!
HI
If you use single PCF8576C no the cascaded application,pins SYNC and CLK must be left open circuit.
Thanks!
Thank you!
Is it mandatory to leave them open circuit or can I also pull/push them to Vdd/Vss ?
