LPIT TMR_CUR_VAL sporadically returning 0xFFFF'FFFF

Question asked by Maddin Hoffmann on Apr 10, 2018

We are using one LPIT channel as free running counter to measure execution times.

Sporadically, the LPIT current value register returns 0xFFFF'FFFF, although the actual counter value is different.

The counter reload value is not equal to 0xFFFF'FFFF, so I don't expect to read this value at all, while the timer is running.

 

 

DBG_EN and DOZE_EN are set to 0.

 

 

Is there any known issure regarding the LPIT timer wrt. to the described behavior?

 

Thanks!

Martin
