7.1.1 Command: initialize
7.1 Commands of PCA9620
The PCA9620 is a versatile peripheral device designed to interface any microprocessor or
microcontroller to a wide variety of LCDs. It can directly drive any static or multiplexed
LCD containing up to 480 elements.
The PCA9620 is controlled by 22 commands, which are defined in
combinations of operation code bits that are not mentioned in this document may lead to
undesired operation modes of PCA9620.
Table 4.
This command generates a chip wide reset which resets all command values to their
default values (see
After this command is sent, it is possible to send additional commands without the need to
re-initialize the interface. Reset takes 100 ns to complete.
