In large display configurations, up to 16 PCF8576s can be
distinguished on the same I 2 C-bus by using the 3-bit
hardware subaddress (A0, A1 and A2) and the
programmable I 2 C-bus slave address (SA0). When
cascaded PCF8576s are synchronized so that they can

electrodes of the display. The other PCF8576s of the
cascade contribute additional segment outputs but their
backplane outputs are left open-circuit (see Fig.18).
The SYNC line is provided to maintain the correct
synchronization between all cascaded PCF8576s. This
synchronization is guaranteed after the Power-on reset.
The only time that SYNC is likely to be needed is if
synchronization is accidentally lost (e.g. by noise in
adverse electrical environments; or by the definition of a
multiplex mode when PCF8576s with differing SA0 levels
are cascaded). SYNC is organized as an input/output pin;

The display controller executes the commands identified
by the command decoder. It contains the status registers
of the PCF8576 and co-ordinates their effects. The
controller is also responsible for loading display data into

and monitors the SYNC line at all other times. Should
synchronization in the cascade be lost, it will be restored
by the first PCF8576 to assert SYNC. The timing
relationship between the backplane waveforms and the
SYNC signal for the various drive modes of the PCF8576
are shown in Fig.19.

chip-on-glass cascading, see Chapter 12.
