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.
