Reading the Pin Value
Wired-AND
Figure 13-6. Output configuration - Wired-OR with optional pull-down.
In the wired-AND configuration, the pin will be driven low when the corresponding bits in the
OUT and DIR registers are written to zero. When the OUT register is set to one, the pin is
released allowing the pin to be pulled high with the internal or an external pull-resistor. If internal
pull-up is used, this is also active if the pin is set as input.

Independent of the pin data direction, the pin value can be read from the IN register, as shown in

delay on the internal signal line.

propagation delays are denoted as t
