Detailed Errata Description

– Scenario 2 (CoXXX Instructions): The compiler (including the intrinsics)

currently does not use the [IDXi*] addressing-mode.

Workaround (Scenario 1)

• On assembler level, do not perform a context switch of the global register

bank in case locations in the DPRAM corresponding to the location of a

register Rx with an odd register number are written by software (see

example for critical scenario in Figure 1).

• With the compiler of the TASKING VX-toolset, do not use the

__registerbank(...) function qualifier to define a global register

bank.

• With the compiler of the “Classic” TASKING C166/ST10 toolset, no

workaround for this scenario is required (see analysis above).

• With the compiler of the Keil C166 toolset, no workaround for this scenario

is required (see analysis above).

Workaround (Scenario 2)

• On assembler level, do not use the CoXXX instructions CoABS, CoADD*,

CoCMP, CoLOAD*, CoMAC*, CoMAX, CoMIN, CoMUL*, CoSUB* with the

addressing mode [IDXi*], [RWm*]. Instead, use e.g. the other addressing

modes of these instructions.

• For compilers of the Keil and TASKING toolsets, no workaround is required

(see analysis above).

Usage of 3rd Party Software

When using operating systems and/or other 3rd party software or libraries,

please check with your supplier.

EBC_X.007 Bus Arbitration not Properly Working

Due to a mismatch of pad propagation delays and internal operation cycle time

the arbitration feature of the External Bus Controller (EBC) can only be used

with severe restrictions. It is recommended not to use this feature, as future

members of the XC2000/XE166 Family will no longer support bus arbitration.
