TMS320F280025C: About Flash interrupts, what‘s the defination of MPOST and FMC interrupts

Part Number: TMS320F280025C

hi, experts 

    may you have a nice day!

     I  am studying 280025c trm, and I am confused with MPOST and FMC interrupts in INT group 12, because I cannot find the  explaination about them.

may  I  missed something, can anyone tell me?

    1. what events can trigger them;

     2. how to enable/disable them;

     3. is any flag for them?

      looking forward to your reply, thanks a lot!

    Hi Matt,

    MPOST is a BOOTROM function enabled through GPREG2 configuration via security settings. Interrupts for MPOST are not enabled, so you will not see the interrupt flag generated.

    All the Flash write/erase operation can generate FMC interrupt, but the Flash library do not enable these interrupts, so you do not need to worry about it.

    May I know what are you trying to do with MPOST/FMC where you need to enable interrupt and have an ISR?

    Best Regards,

    Nirav

    I just want to test the 280025's extreme performance to get the most out of it in the system.

    thank you very much！
