the configuration port’s registers in the middle of an RMAP write command. This needs to be consid-
ered in order to avoid a mismatch between the expected written value and actual written value.
None of the access control mechanisms mentioned in section 13.5.1.3 have any effect on the AHB
slave interface.
13.5.3 Registers
The configuration port’s registers listed in this section can be accessed either through the RMAP tar-
get, or the AMBA AHB slave interface. The address specified in table 174 is the RMAP address.
When accessed through the AHB slave interface, the address in the table should be added to the
router’s base address specified in table 7, section 2.3. Registers that exist in several identical copies,
corresponding to different addresses or ports, for example the RTR.RTPMAP registers, are only
described once. The register layout used is explained in section 1.11.
