[1]
Default value.
8.1.3.2
Command: Set_VLCD_A and Set_VLCD_B
The Set_VLCD_A and Set_VLCD_B commands allow programming the VLCD value of the
character and icon mode, respectively. The generated VLCD is independent of the power
supply, allowing battery operation of the PCA2117.

Default value.
8.1.4 Temperature compensation control commands
8.1.4.1
Command: Temperature_ctrl
The Temperature_ctrl command enables or disables the temperature measurement block
and the temperature compensation of VLCD (see Section 8.4.5).
