Alternate Functions of Port D
ATmega169A/PA/329A/PA/3290A/PA/649A/P/6490A/P
Table 14-11. Overriding Signals for Alternate Functions in PC3:PC0
The Port D pins with alternate functions are shown in
Table 14-12. Port D Pins Alternate Functions (SEG refers to 100-pin/64-pin pinout)
The alternate pin configuration is as follows:
• SEG – Port D, Bit 7:2
SEG, LCD front plane 19/15-24/20.
• INT0/SEG – Port D, Bit 1
INT0, External Interrupt Source 0. The PD1 pin can serve as an external interrupt source to the
MCU.
SEG, LCD front plane 25/21.
• ICP1/SEG – Port D, Bit 0
ICP1 – Input Capture pin1: The PD0 pin can act as an Input Capture pin for Timer/Counter1.
SEG, LCD front plane 26/22
