Alternate Functions of Port A
62
ATmega169/V
• Bit 4 – PUD: Pull-up Disable
When this bit is written to one, the pull-ups in the I/O ports are disabled even if the DDxn
and PORTxn Registers are configured to enable the pull-ups ({DDxn, PORTxn} = 0b01).
See “Configuring the Pin” on page 56 for more details about this feature.
The Port A has an alternate function as COM0:3 and SEG0:3 for the LCD Controller.
Table 27. Port A Pins Alternate Functions
Table 28 and Table 29 relates the alternate functions of Port A to the overriding signals
shown in Figure 26 on page 60.
