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:
