Hello WoRo!

I had your same question when I wanted to read TIM1_CNTR.

I found a reply to my question at the bottom of page 136 of  STM8S family reference manual (RM0016):

''Do not use the LDW instruction to read the 16-bit counter. It reads the LS byte first and returns an incorrect result''

So, if RM0016 tells the truth, a LDW instruction loads the lower byte first.
