Universal LCD driver for low multiplex rates
Excessive capacitive coupling between SCL or CLK and SYNC may cause erroneous synchronization. If this proves to be a problem, the capacitance
of the SYNC line should be increased (e.g. by an external capacitor between SYNC and V
be countered by an external pull-up resistor.
