1. Each cell represents one register with individual configuration bits
23.0.6
23.0.6.1
This register holds the value driven out to the pin if the pin is used as a general purpose I/O.
Writing to this register has only an effect on the pin if the pin is used as general purpose output.
When reading this address, the buffered state of the pin is returned if the associated data direction
register bit is set to “0”.
If the data direction register bits are set to logic level “1”, the contents of the data register is
returned. This is independent of any other configuration
23.0.6.2
This is a read-only register and always returns the buffered state of the pin
23.0.6.3
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
