6.4.1
CPU accesses to internal and external busses, thus internal or external memories or
peripherals are controlled with the respective address ranges. These address ranges are
supported for on-chip XBUS resources or for external off-chip resources. In INCA-D four
address ranges with according bus definitions must be programmed for on-chip XBUS
peripherals (including memories) .
Address ranges and thus address mappings of peripherals, which communicate over the
internal XBUS are controlled by address selection registers XADRSx. The respective
bus type definitions are controlled with registers XBCONx.
Generally, the definition for the XADRSx and XBCONx registers is very similar to the
defintion of the registers of the External Bus Interface. The XADRSx registers and
XBCONx registers are defined as follows:
XADRS1(2)(3)(4)
