This is a read/write register and is not affected by reset. The bits may be
read and written at any time, but, when a pin is allocated to its alternate
function, a write to the corresponding register bit has no affect on the pin
state.
DDH[7:0] — Data direction for port H
Three of the ports (B, F and G) have internal, software selectable pull-up
resistors. Port H has both pull-up and pull-down resistors, as described
below.
