Port D Schematics

ATmega103(L)
• IC1 – Port D, Bit 4
IC1, Input Capture pin for Timer/Counter1. When a positive or negative (selectable)
edge is applied to this pin, the contents of Timer/Counter1 is transferred to the
Timer/Counter1 Input Capture Register. The pin has to be configured as an input to
serve this function. See the Timer/Counter1 description on how to operate this function.
The internal pull-up MOS resistor can be activated as described above.
• T1 – Port D, Bit 6
T1, Timer/Counter1 counter source. See the Timer description for further details.
• T2 – Port D, Bit 7
T2, Timer/Counter2 counter source. See the Timer description for further details.
Note that all port pins are synchronized. The synchronization latches are, however, not
shown in the figures.
