Why seems is only 5 timers - TM4C1294NCPDT and Rev 14 datasheet suggest are 8.

Hello BP101

What does the SYSCTL.PPTIMER register read back as.

Hi Amit,
Hey that is a great point - the PRTIMER shows 8 timers 0-7 and all are ready but the debug register view only list 5 timers. Made sure to enable the timer block peripheral 7 before assigning it over from TM4 for (cpu_usage.c) but it caused exception non the less.

Same thing in PinMux tool only show the timers with CCP0/1 pins. So there are 8 useable timers but only 5 actually have CCPx pins.

And while, "More the merrier" that's not (usually) a fatal shortcoming.

In the olde dayze - when dinosaurs & 8 bit MCUs roamed - we used Timers based upon, "Non Timer pin triggers."   (i.e. some other GPIO pin)

Indeed you lose some of the "auto-features" which the "more complete" Timers provide - yet you're clever/motivated enough to overcome.

At some point you must accept - that which is...is!

Our bp claimed "5" - oh well.

May we note that there are, "Only 6 w/"direct" IO capability?"

Past (or present) any MCU pin toggle may trigger an interrupt - and that interrupt's "service" may enable one (or more) Timers.

Surely not as "neat/clean" as the more complete Timer (w/IO) but as we sailor's (sometimes) say - "Any port (GPIO) in a storm (Timer shortage)."

Hello cb1

Yes. And a timer interrupt may toggle the pin as well.

Hi Amit,

Yea forgot there was TM0 in there -  debug was showing 6 ending on TM5 and the GEL file was maybe out of date?

I manually added the TM6/7 into the GEL for now.

Yet the cut/paste reveals NO such TM6/TM7 addition - that we can see...

TM6/7 were there already separated by many lines in both the GEL and Debug register view.

Seems those two lonely guys were given addresses the others just couldn't send mail to. As for me well never go searching very far from the group at hand others become invisible and just don't compute to any given logic. Now transparent know they hang near the bottom of the list never visible naked eye last two years were simply gone missing.

Have you considered drafting a, "Letter of complaint?"

Hello BP101

I am using the latest CCS version 6.1 and the gel file is an updated one.
