Input/Output (I/O) Ports
When DDREx is a logic 1, reading address $0008 reads the PTEx data latch. When DDREx is a logic 0,
reading address $0008 reads the voltage level on the pin. The data latch can always be written,
regardless of the state of its data direction bit.

DDRE Bit
1. X = don’t care.
2. Hi-Z = high impedance.
3. Writing affects data register, but does not affect the input.
