In single-chip or bootstrap modes, port B pins are general-purpose
outputs. In expanded or special test modes, port B pins are high-order
address outputs.
In single-chip and bootstrap modes, port C pins reset to high-impedance
inputs. (DDRC bits are set to 0.) In expanded and special test modes,
port C pins are multiplexed address/data bus and the port C register
address is treated as an external memory location.
