Table 25. DDCn Effects on Port C Pins
Note:
Port C Schematics
Note that all port pins are synchronized. The synchronization latch is however, not shown in the figure.
Figure 56. Port C Schematic Diagrams (Pins PC0 - PC5)
Port D
Port D is an 8 bit bi-directional I/O port with internal pull-up resistors.
Three I/O memory address locations are allocated for Port D, one each for the Data Register - PORTD, $12($32), Data
Direction Register - DDRD, $11($31) and the Port D Input Pins - PIND, $10($30). The Port D Input Pins address is read
only, while the Data Register and the Data Direction Register are read/write.
The Port D output buffers can sink 20 mA. As inputs, Port D pins that are externally pulled low will source current if the pull-
up resistors are activated.
Some Port D pins have alternate functions as shown in the following table:
