5. Mode 7
Figure E-5 shows how the pin states change when the RES pin goes Low in mode 7.
As soon as RES goes Low, all ports are initialized to the input (high-impedance) state.
The clock output pins P1
RES pin is sampled. Both pins are initialized to the output state.

The dotted line indicates that P1 /ø and P1 /E are input ports if the corresponding DDR
bit is 0, but clock output pins if the DDR bit is 1.
