Technical Data
When bit DDRGx is a logic 1, reading address $000A reads the PTGx
data latch. When bit DDRGx is a logic 0, reading address $000A reads
the voltage level on the pin. The data latch can always be written,
regardless of the state of its data direction bit.

X = Don’t care
Hi-Z = High impedance
1. Writing affects data register, but does not affect input.
