8.1.1 Command: initialize
8.1 Commands of PCF8536
The PCF8536 is a versatile peripheral device designed to interface any microcontroller to
a wide variety of LCDs and 6 backlight LEDs. It can directly drive any multiplexed LCD
containing up to eight backplanes and up to 44 segments.
The PCF8536 is controlled by 15 commands, which are defined in
combinations of operation code bits that are not mentioned in this document may lead to
undesired operation modes of PCF8536.
This command generates a chip-wide reset. It has the same function as the RESET pin.
Reset takes 1 ms to complete.
