MSP430F5336: 16 bit Timer capture interrupt

Prasannal Naik

Part Number: MSP430F5336

Hello,

I have a query regarding 16-bit Timer of MSP430F5336 and its associated capture inputs. Is there any possibility of missing the timer overflow interrupt while using the timer module in capture mode?

I am planning to measure frequency of a source(i.e. function generator generating a square wave of 50Hz and 50% duty cycle)

Thanks,

Hi Prasanna,

in case you're checking for the Timer Interrupt, Overflow Flag inside the interrupt service routine you'll be aware of the timer overflow. Still, you'll handle the Capture/Compare Interrupt Flag and the Overflow Flag in the same isr so you could have a delay (the Timer Overflow, Interrupt Flag has lowest priority of the Timer interrupts) until the Capture/Compare interrupt handling is terminated.

Best regards,
Britta

Hi Prasanna,

as I didn't hear back from you I assume that the issue has been solved on your end.
Please note that I'm closing this thread but that replying back to it will re-open it if needed.

Best regards,
Britta
