Pad Definition

AirPrime HL77xx pads are divided into 2 functional categories.
Core functions and associated pads cover all the mandatory features for M2M connectivity and will be available by default across all CF
•
modules. These Core functions are always available and always at the same physical pad locations. A customer platform using only these functions
and associated pads are guaranteed to be forward and/or backward compatible with the next generation of CF
• Extension functions and associated pads bring additional capabilities to the customer. Whenever an Extension function is available on a module, it
is always at the same pad location.
Other pads marked as "not connected" or "reserved" should not be used.
