Fig 31. Synchronization of the cascade for the various PCF8576C drive modes
Excessive capacitive coupling between SCL or CLK and SYNC will cause erroneous
synchronization. If this is a problem you can increase the capacitance of the SYNC line (e.g. by an
external capacitor between SYNC and V
can be countered by an external pull-up resistor.
