ATmega169V/L
• Bits 7:4 – Res: Reserved Bits
These bits are reserved bits in the ATmega169 and will always read as zero.
• Bits 3:0 – LCDCC3:0: LCD Contrast Control
The LCDCC3:0 bits determine the maximum voltage VLCD on segment and common
pins. The different selections are shown in Table 99. New values take effect every
beginning of a new frame.
