A pull-up device is connected to the associated port J pin, if enabled by the associated bit in register PERJ
and if the port is used as general purpose input or as IIC port.
A pull-down device is connected to the associated port J pin, if enabled by the associated bit in register PERJ
and if the port is used as input.
