From LCDADJ0 and LCDADJ12 fuses:
The above equations describe the nominal value of VLCD for a specific LCD_DAC value. The
specifications below list the maximum deviation between actual VLCD and VLCDnom. Note that when
VCC and boost are insufficient, the LCD DAC will not reach its target value and a large negative error
will occur.
