SEC Self-nesting on BF-70x

Hi,

 

I have a question about SEC(System Event Controller) self-nesting interrupt.

 

For instance two timers (timer0 and timer1) are set in SEC interrupt source (SEC Priority : timer0 > timer1).

 

When the timer0 interrupt is asserted , while running the timer1 ISR(interrupt service routine ).

 

Immediately PC jumps to IVG11 handler, and call the timer0 ISR, even the timer1 ISR is not completed.

 

Is it correct specification as SEC self-nesting interrupt?

 

Best regards,

Tatsuhiro Ujihara
