Remark: In direct mode, no external V
The direct mode can be used to reduce the current consumption when the required output
voltage V
in MUX 1:9 (depending on LCD liquid properties).

The bit-field TC[1:0] selects the temperature coefficient for the internally generated
V

Table 30.
A software configurable voltage multiplier is incorporated in the V
be set via the HV_gen command. The voltage multiplier control can be used to reduce
current consumption by disconnecting internal voltage multiplier stages, depending on the
required V
