Chapter 24 DG128 Port Integration Module (S12XDG128PIMV2)
24.0.5.46 Port H Pull Device Enable Register (PERH)
Read: Anytime.
Write: Anytime.
This register configures whether a pull-up or a pull-down device is activated, if the port is used as input.
This bit has no effect if the port is used as output. Out of reset no pull device is enabled.
24.0.5.47 Port H Polarity Select Register (PPSH)
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.
