Chapter 22 DP512 Port Integration Module (S12XDP512PIMV2)
22.4.1.2
This is a read-only register and always returns the buffered state of the pin
22.4.1.3
This register defines whether the pin is used as an input or an output.
If a peripheral module controls the pin the contents of the data direction register is ignored
22.4.1.4
If the pin is used as an output this register allows the configuration of the drive strength.
22.4.1.5
This register turns on a pull-up or pull-down device. It becomes active only if the pin is used as an input
or as a wired-OR output.
22.4.1.6
This register selects either a pull-up or pull-down device if enabled. It becomes active only if the pin is
used as an input. A pull-up device can be activated if the pin is used as a wired-OR output. If the pin is
used as an interrupt input this register selects the active interrupt edge.
22.4.1.7
If the pin is used as an output this register turns off the active high drive. This allows wired-OR type
connections of outputs.
