I found the following infomation in "Datapath Configuration Tool Cheat Sheet_001-86838.pdf" page 9
Compare block 0 can compare only D0 and a masked value from A0.
but when you run the software: Datapath Configuration Tool,
you can find CFG13-12 CMP SELA has many choice, none of them are A0_D0. I think this is a software bug.
please correct it.

Hi Teddy,
you have to read it complete:
CMP SELB & CMP SEL A
Configures the Comparison B and
Comparison A Options for compare
block >>>1<<<. The CMP SEL field of the RAM
configuration determines if the A or B
option is in effect for a given cycle.
Note: Compare block 0 can compare
only D0 and a masked value from A0.
Regards,
Ralf

Hi,
Thanks for your reply.
I took for granted CMP SELA is for COMPARE BLOCK 0 and CMP SELB is for COMPARE BLOCK 1.
You are right, that is my misunderstanding.
Best regards.
Teddy
