Mask Set Errata for Mask 1N03P

Hello !

 

Do I undestand right and "Mask Set Errata for Mask 1N03P Rev. 09 Sept 2015" is the latest one what available for K82 MCU ?

 

On my K82 I can see 1N03P  sign.

 

As result all interrupt handlers should have this code at the end of routine:

 

/* Add for ARM errata 838869, affects Cortex-M4, Cortex-M4F Store immediate overlapping
exception return operation might vector to incorrect interrupt */
#if defined __CORTEX_M && (__CORTEX_M == 4U)
__DSB();
#endif

 

Or may be even:

 

__DSB();

__ISB();

 

 

Regards,

Eugene
