4.5.1 PORTC — Port C data register

Port C data (PORTC)
Port C is an 8-bit bidirectional port, with both data and data direction
registers. In addition to their I/O capability, port C pins are used as the
nonmultiplexed data bus pins, as shown in the following table.
The state of the pins on reset is mode dependent. In single chip or
bootstrap mode, port C pins are high-impedance inputs. In expanded or
test modes, port C pins are the data bus I/O and PORTC/DDRC are not
in the memory map.
The bits may be read and written at any time and are not affected by
reset.
