Hi all,

i'm using STM32F407 with 12MHz ext. crystal with 168MHz system clock, i use demo for STM32F4Discovery,

i configured Timer4 and Timer8 in same way,
specifically: ARR=1, PSC=0, CKD=0,
and i'm measuring 42MHz on both timers,
is it something worng configured ?
Timer8 is on APB2 so it should be twice faster than Timer4 , shouldn't be ?

please help me to understand,

Kind regards,
