8.2.3 Recommended start-up sequences
The first command sent to the device after the power-on event must be the initialize
command (see
After Power-On Reset (POR) and before enabling the display, the RAM content should be
brought to a defined state by writing meaningful content (e.g. a graphic) otherwise
unwanted display artifacts may appear on the display.
The RESET pin of the PCF8536 will reset all the registers to their default state. The reset

is removed, the PCF8536 will behave in the same manner as after Power-On Reset
(POR). See
This chapter describes how to proceed with the initialization of the chip in different
application modes.
In general, the sequence should always be:
