Hi all,
I wonder what is Program cached & non-cached access in AURIX?
Thank you for your replies and regards,

Hi Christine,
In general, it allows 2 types of access to the flash in AURIX, cached & non-cached access. By using cached access, these improve performance and reduce significantly average access time for memories using cacheable segments.
By default the program cache is not turned on in the CPU. However if enable it by configuring PCBYP correctly, and link your code to the cached area of memory (e.g. 0x80000000 instead of 0xA0000000 for internal flash), then the program cache is enabled.
Best regards
