The information from the datasheet is quite limited regarding this issue:
Illegal Word Operand Access Trap (B): Whenever a word operand read or write
access (including Flash commands!) is attempted to an odd byte address, the
ILLOPA flag in register TFR is set and the CPU enters the illegal word operand
access trap routine.
What may trigger this trap and shouldn't the compiler generate clean code in order this not to happen? And how do I exit the trap function in a decent way, so that my program can continue? Because right now, it just seems to get stuck, even if I have my own defined trap routine.
Thanks in advance,

Show LessDo you have an idea how this PN MB9BF122MPMC-G-JNE2 is packaging and ship out?
Are they shipped in trays of 119 and each tray has its own lid?
Per customer's warehouse:
We received a package of 595pcs and needed for a previous shipment only 476pcs with mfr packaging. For that first shipment we used 4trays + 1 empty top tray.
The result was that we had one tray with 119pcs where we missed an empty top tray. In that case we change the trays to a non mfr tray and repack the parts.
I hope that makes clear why we have them with non mfr trays on stock.

Show LessWe have plan to used XC2268N, but I can not find XC2268N Dip file for DAVE2.
I confirmed XC2236N, XC2238N, XC2265N in the XC22xxN DIP file.
there is a difference in package between xc2236N(QFP 64) and xc2268N(QFP 100)
there is a difference in CAN node between xc2265N(3 node) and XC2268N(6 node)
How to use XC2268N in the dave2?
How can I get the XC2268N Dip file or another method to used DAVE2 for XC2268N?
Best Regard.

Hello, I am doing my first project with Cypress MCU-I want to communicate with nRF24L01 tranceiver via SPI. I am using CSIO in SPI mode from PDL 2.1.0, but then I try to build the project with Keil I get message ".\output\release\s6e2ccxj_template.axf: Error: L6218E: Undefined symbol PINRELOC_SET_EPFR (referred from main.o)." There were a lot more, but I figured out it was because definitions between .h files were lacking so I managed to solve all errors but this one because I had not found definition of PINRELOC_SET_EPFR so I am asking maybe someone could help with this problem? Maybe I am doing it all wrong? I will add my project file to the post.
Show LessHello,
a customer is asking me to freely change an image Logo through a USB Mass Storage.
I wrote the code to read from the USB Mass Storage, and it works fine.
My problem is to change the Logo image.
Consider that this logo always resides in the very begininng of the HyperFlash (that should be at address 0xC0000000) and that it is a 480x272 pixel 24bpp BMP, so the whole size, including the header, is 391700 bytes (20 bytes for the header and 391680 bytes for the bitmap data).
I tried many examples without success, both from sample codes and from datasheets (for example AN218684).
My hardware and software configuaration is exactly the same as per the FM4-176L-S6E2DH eval board).
Can you suggest me a solution?
Thank you very much in advance
Regards
GianLuca
