4.4 Programming Interface
4.4.1 Access Control Logic (Address Decoder)
All the resources of the CP383 are mapped within the 64 kB PCI memory address space which
itself is set in the PCI configuration register BAR0. The port size of all local or backend registers
is 32-bit by default. The address map of the registers is as follows.
