REGISTER MAP
All the P95020 control and status registers accessible to the Microprocessor are mapped to a 1024 location address
space. This address space maps to:
4 x 256 Bytes of IC pages for the IC slave interface
1024 consecutive addresses in the embedded Microprocessor address space
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.
Each Module is allocated a consecutive address space.
Register address computation: Address = Base Address + Offset Address
The Base addresses (for both IC and embedded uP) are listed in the following table. The Offset addresses are defined in
different functional Modules. The offset address is labeled as
“Offset Address” in the Module Register definition sections.
