The Low Power Mode output table

The following table provides this Low Power Mode signal out behavior 
by the keypad MFPs:
DKINs:  Float ("Z").  (They are all pulled low by the platform 
unless driven by the scroll wheel.)
MKINs:  Float ("Z").  (They are all pulled low by the platform unless
driven by connection with an MKOUT due to key press.)
MKOUTs: Driven high output to provide edge triggering 
capability on the MKINs if a matrix key is pressed.
Note that this is desirable only if wakeup from keypress
is intended.  Otherwise, they should probably be pulled 
low so that no power would be wasted if a key is pressed
and a connection is made with an MKIN.

It is useful for the keypad module to maintain a separate list of actual 
wake up trigger MFPs in the event that the scroll wheel unit will not 
be powered during low power modes.  In that case, it would be undesirable 
to arm the wake up trigger for the DKINs in case a transition occurs on 
entry to the LPM as power is removed.
This list is used to disable/clear the wake up triggers on the included
MFPs and also to enable / arm the wake up triggers on them.
