The first command sent to the device after the power-on event must be the initialize
command (see Section 8.1.1 ).
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.
8.2.2 RESET pin function
The RESET pin of the PCF8536 will reset all the registers to their default state. The reset
state is given in Table 29 . The RAM contents will remain unchanged. After the reset signal
is removed, the PCF8536 will behave in the same manner as after Power-On Reset
(POR). See Section 8.2.1 for details.
8.2.3 Recommended start-up sequences
This chapter describes how to proceed with the initialization of the chip in different
application modes.
In general, the sequence should always be:
1. Power-on the device,
2. set the display and functional modes,
3. fill the display memory and then
4. turn on the display.
