Definition of Address Areas
The four register pairs BUSCON4/ADDRSEL4...BUSCON1/ADDRSEL1 allow to define
4 separate address areas within the address space of the INCA-D. Within each of these
address areas external accesses can be controlled by one of the four different bus
modes, independent of each other and of the bus mode specified in register BUSCON0.
Each ADDRSELx register in a way cuts out an address window, within which the
parameters in register BUSCONx are used to control external accesses. The range start
address of such a window defines the upper address bits, which are not used within the
address window of the specified size (see table below). For a given window size only
those upper address bits of the start address are used (marked “R”), which are not
implicitly used for addresses inside the window. The lower bits of the start address
(marked “x”) are disregarded.

Address Window Arbitration
For each access the EBC compares the current address with all address select registers
( ADDRSELx and XADRSx). This comparison is done in four levels.
Priority 1: The XADRSx registers are evaluated first. A match with one of these registers directs
Priority 2: Registers ADDRSEL2 and ADDRSEL4 are evaluated before ADDRSEL1 and
Priority 3: A match with registers ADDRSEL1 or ADDRSEL3 directs the access to the respective
