TIM16B8CV2 override mode

Hi all.

 

Here are questions about TIM in 9s12 and especialy about the OC7M and OC7D registers.

 

First question :

Looking at datasheet (S12XS Family reference manual Rev 1.13) page 474, the table 16-10 shows : TC7>TCX or TC7=TCX.

But output compare mode explanations (page 485) talk about channel 7 event (either overflow of free running counter if TTOV7 is set or succesfull output compare) that trigger override mode.

 

Therefore i don't understand witch one is true. I believe that there is a mistake page 474 and that the right text should be TC7 not equal to TCNT or TC7=TCNT.

 

Second question :

Also what does mean OC7Dx + OMx/OLx (page 474) I believe it means that first IOCx = OC7Dx and then the value is affected by OMx/OLx if TCx = TCNT.

Am I right ?

 

Thank to all.

Greetings
