Port D
Port D is a 2-bit bi-directional I/O port. Its output buffers can sink or source 2 mA.
Three I/O memory address locations are allocated for the Port D, one each for the Data Regis-
ter - 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.
Port D Data Register – PORTD
Port D Data Direction Register – DDRD
Port D Input Pins Address – PIND
The Port D Input Pins address (PIND) is not a register, and this address enables access to the
physical value on each Port D pin. When reading PORTD, the Port D Data Latch is read, and
when reading PIND, the logical values present on the pins are read.
