F37x documentation inconsistency--comparator port B

Which to believe--

STM32F32x datasheet (Sept, Doc ID 022691):

Page 40, Table 15, Alternate functions for port PB, shows COMP1_OUT and COMP2_OUT for AF8 on PB8 and PB9. Table 14, port PA, shows PA0/PA6/PA11 and PA2/PA7/PA12. (Table 13, pin definitions, is also consistent with Tables 13 & 14.)

Ref Manual (RM0313, Sept, Doc ID 022448 Rev 1):

Page 276, fig 51, shows only PA0/PA6/PA11 and PA2/PA7/PA12, with no mention of the port B pins.

My guess is that the datasheet is more likely correct than the ref manual. I don't want to get too far down the road with the design and find that my guess was wrong. (Maybe this is why it is called the f3-Discovery board--one needs it to discover how the part really works...)

Here is the reply from ST--

Dear User,

Please find here below latest information concerning the request R12410061

I have checked with the factory and they confirmed that the data sheet is correct, the ref manual will be updated.

Thanks for pointing out this omission in our ref manual.
