Really strange problem configuring the PCA

Thomas Stathes

Hello all,
This is a really strange problem i have just encountered.

to simplify i am trying to load values AABB CCDD EEFF into the pca capture regs.

So the code to do this should simply be:

PCA0CPL0 = 0xBB; PCA0CPL1 = 0xDD; PCA0CPL2 = 0xFF; PCA0CPH0 = 0xAA; PCA0CPH1 = 0xCC; PCA0CPH2 = 0xEE;
(this is generate by config2)

however when using the debugger i can see that

PCA0CP0 = 0xCCBB

PCA0CP1 = 0xEEDD

PCA0CP2 = 0xAAFF

It looks like miss-mapped registers.

So my question is, is this a known issue with the header file? Are there any other known issues like this?
Thanks,
Tom

    But it's the chip that is the "original".

    And the simulator tries to match the original as best as possible.

    Have you verified that the header file is matching the datasheet for the processor?

    Another thing - the debugger is showing you information based on a configuration file. And if this configuration file is wrong (likely having the same error as the simulator) then what you see will not match the reality.
