When bit DDREx is a logic 1, reading address $0008 reads the PTEx data latch. When bit 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.

Notes:
DDRE Bit
1. X = Don’t care
2. Hi-Z = High impedance
3. Writing affects data register, but does not affect input.
