6�3�10�- DEVICE CONFIGURATION VARIABLES
The following functions are implemented for these variables:
Function 0x04 : reading registers.
Function 0x10 : Writing multiple registers.
Note: The programming values must be written in hexadecimal.
It is necessary to change the screen when a setup change is made for communi-
cations in order for the changes take effect in the display.
6�3�10�1�- Date and time
These parameters occupy 1 register each.
