Product data sheet
Table 21.
In the cascaded applications, the OSC pin of the PCA85132 with subaddress 0 is
connected to V
the CLK pin. The other PCA85132 devices are having the OSC pin connected to V
meaning that these devices are ready to receive external clock, the signal being provided
by the device with subaddress 0.
In the case that the master is providing the clock signal to the slave devices, care must be
taken that the sending of display enable or disable will be received by both, the master
and the slaves at the same time. When the display is disabled the output from pin CLK is
disabled too. The disconnection of the clock may result in a DC component for the display.
Alternatively, the schematic can be also constructed such that all the devices have OSC
pin connected to V
connected to the same external CLK).
