This register configures whether a pull-up or a pull-down device is activated, if the port is used as
input or as wired-OR output. This bit has no effect if the port is used as push-pull output. Out of
reset a pull-up device is enabled.
Field
23.0.5.59 Port J Polarity Select Register (PPSJ)
Read: Anytime.
Write: Anytime.
This register serves a dual purpose by selecting the polarity of the active interrupt edge as well as
selecting a pull-up or pull-down device if enabled.

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.
