Table 94. LCD Duty Select
Note:
• Bit3 – Res: Reserved Bit
This bit is reserved bit in the ATmega169 and will always read as zero.
• Bits 2:0 – LCDPM2:0: LCD Port Mask
The LCDPM2:0 bits determine the number of port pins to be used as segment drivers.
The different selections are shown in Table 95. Unused pins can be used as ordinary
port pins.

• Bit 7 – Res: Reserved Bit
This bit is reserved bit in the ATmega169 and will always read as zero.
• Bits 6:4 – LCDPS2:0: LCD Prescaler Select
The LCDPS2:0 bits selects tap point from a prescaler. The prescaled output can be fur-
ther divided by setting the clock divide bits (LCDCD2:0). The different selections are
shown in Table 96. Together they determine the prescaled LCD clock (clk
is clocking the LCD module.
