OCDS_TC.H004 Device Identification by Application Software
While each device type can easily be recognized by test equipment using the
JTAG ID, over the years each device family has had a proprietary way to
provide the same information to application software running on the device.
When reusing software for another device family the algorithm had to be
adapted.
To worsen things, using the wrong algorithm may cause fatal errors, e.g. traps
when accessing illegal addresses.
Starting with the Audo Future family the JTAG ID as available as a standard
SFR (CBS_JTAGID) at a fixed address, namely in the address space of the
“main” Cerberus. The value found in this register unambiguously defines where
additional information (e.g. CHIPID) can be found in the device on hand.
Older devices obviously do not have the CBS_JTAGID, so accessing its
address may cause problems.
Workaround
Each Cerberus module ever implemented has a version number mapped into a
register (CBS_JDPID) at a fixed address (0xF0000408).
Note: This register is not published in all user manual versions.

PCP_TC.H004 Invalid parity error generated by FPI write to PRAM
If an FPI write is performed to a PRAM location that contains a parity error then
the PCP generates a memory error when it should not.

If the version number found in this register (CBS_JDPID[7:0]) is less than
0x50, no CBS_JTAGID register is provided. The original software algorithm
shall be employed by the reused software.
If the version number found in this register (CBS_JDPID[7:0]) is 0x50 or
higher, the content of the CBS_JTAGID register shall be used to select the
proper algorithm.
