   POWERSCAN™ PD/PM96XX
Enable/disable buttons
This feature offers the ability to enable or disable the keypad.
It  is  possible  to  set  values    between  0x0000  to  0xFFFF.  Each  bit  corresponds  to  the
enabling (value 1) or disabling (value 0) of a key [the values   are a mask associated with
each key 1111 1111 1111 1111].
For  4-key  models,  the  valid  range  for  enabling/disabling  the  keys  is  from  0x0000  to
0xF000.
The association between the bits and the keys is illustrated in the following table:
