8.1.4.1 Backplane swapping

Backplane swapping can be configured with the BPS bit (see Table 8). It moves the

location of the backplane and the associated segment outputs from one side of the

PCF8536 to the other. Backplane swapping is sometimes desirable to aid with the routing

of PCBs that do not use multiple layers.

The BPS bit has to be set to the required value before enabling the display. Failure to do

so does not damage the PCF8536 or the display, however unexpected display content

may appear.
