15.7 GLOBAL REGISTER SETTINGS (IC-page 0)
Global Registers are used by the Access Manager, which includes an IC Slave and Bus Arbiter. For easy access from
the IC slave interface (by default 256 Bytes oriented) the first 16 registers of each page are global for all the pages
(Page 0 thru Page 3). The Base addresses are defined in Table 3
– Register Address Global Mapping on page 20.
