When bit DDRHx is a logic 1, reading address $000B reads the PTHx
data latch. When bit DDRHx is a logic 0, reading address $000B reads
the voltage level on the pin. The data latch can always be written,
regardless of the state of its data direction bit.
the operation of the port H pins.
X = don’t care
Hi-Z = high impedance
1. Writing affects data register, but does not affect input.
