6.3 Port B
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.
6.4 Port C
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.
