F2837xD Flash API: Disabled Interrupts and callback invoke intervals

Dieter Massa

Hi,

Flash API documents for previous C2000 microcontroller generations (e.g. "TMS320F2833x Flash API", Version 2.10) tell that the erase function disables interrupts for 3 - 4ms and the callback function is invoked every 3 - 4 ms.

In the Flash API document for the F2837xD Flash API (Literature Number SPNU595) I did not find sections on callbacks or disabled interrupts. So my questions on the F2837xD flash API functions are:
What are their worst case execution times?
Can they be interrupted?
Do they support callbacks? - if yes: What is the maximum time between callback invokes?

Thanks, Dieter

    Dieter,

    As mentioned in the TRM, for F2837xD devices, Flash API execution is interruptible.  However, there should not be any read/fetch access to the Flash bank when an erase/program operation is in progress.  

    Once the application issues an erase or program command from RAM, application should not access flash until Fapi_checkFsmForReady() returns the status as Fapi_Status_FsmReady indicating that the flash operation is over.

    Thanks and regards,
