3.3.2.4.5
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.
These bits have no effect if the port is used as output. Out of reset no pull device is enabled.
PERH[6:0] — Pull Device Enable Port H
3.3.2.4.6
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.
PPSH[6:0] — Pull Select Port H
Freescale Semiconductor
1 = Either a pull-up or pull-down device is enabled.
0 = Pull-up or pull-down device is disabled.
1 = Rising edge on the associated port H pin sets the associated flag bit in the PIFH register.A
0 = Falling edge on the associated port H pin sets the associated flag bit in the PIFH register.A

pull-down device is connected to the associated port H pin, if enabled by the associated bit in
register PERH and if the port is used as input.
pull-up device is connected to the associated port H pin, if enabled by the associated bit in
register PERH and if the port is used as input.
