Command Type/Register Map
LC822973
There are two types of command. One is to be able to operate by a command itself and the other needs a parameter.
In case of writing a command, A0 should be set to 0 and A0 should be set to 1 in case of writing or reading a parameter.
If other command is executed before setting a parameter, the command that is in the middle of setting is cancelled.
