ATmega169/V
The Port D pins with alternate functions are shown in Table 36.
Table 36. Port D Pins Alternate Functions
The alternate pin configuration is as follows:
• SEG15 - SEG20 – Port D, Bit 7:2
SEG15-SEG20, LCD front plane 15-20.
• INT0/SEG21 – Port D, Bit 1
INT0, External Interrupt Source 0. The PD1 pin can serve as an external interrupt
source to the MCU.
SEG21, LCD front plane 21.
• ICP1/SEG22 – Port D, Bit 0
ICP1 – Input Capture pin1: The PD0 pin can act as an Input Capture pin for
Timer/Counter1.
