PARALLEL I/O
TECHNICAL DATA

DDD[7:0] — Data Direction for Port D
When port D is a general-purpose I/O port, the DDRD register controls the direction of
the I/O pins as follows:
0 = Configures the corresponding port D pin for input
1 = Configures the corresponding port D pin for output
In expanded and test modes, bits 6 and 7 are dedicated AS and R/W outputs.
When port D is functioning with the SPI system enabled, bit 5 is dedicated as the slave
select (SS) input. In SPI slave mode, DDD5 has no meaning or effect. In SPI master
mode, DDD5 affects port D bit 5 as follows:
0 = Port D bit 5 is an error-detect input to the SPI.
1 = Port D bit 5 is configured as a general-purpose output line.
If the SPI is enabled and expects port D bits 2, 3, and 4 (MISO, MOSI, and SCK) to be
inputs, then they are inputs, regardless of the state of DDRD bits 2, 3, and 4. If the SPI
expects port D bits 2, 3, and 4 to be outputs, they are outputs only if DDRD bits 2, 3,
and 4 are set.
DDRA7 — Data Direction Control for Port A Bit 7
PAEN — Pulse Accumulator System Enable
PAMOD — Pulse Accumulator Mode
PEDGE — Pulse Accumulator Edge Control
DDRA3 — Data Direction for Port A Bit 3
Overridden if an output compare function is configured to control the PA3 pin.
0 = Input only
1 = Output
