released. The number of data structures used by the device in reserved areas depends on this
initialization.

7.4 Control Register Descriptions
NOTES:
•
•
All ports marked as “Reserved” must be initialized to 0 at initial setup. Software mod-
ifications to these locations after setup will cause incorrect operation.
All read/write port bits marked “Not used” must be written with the value 0 to main-
tain software compatibility with future versions.
