STM32F CAN messages filtering

Hello,

I would like to ask you for an advice regarding the CAN messages

filtering. I am not sure whether I understand the filtering and masking

in right manner. I have following settings

CAN_FilterConfTypeDef

filt;

filt.

FilterIdHigh

= (0x6C1 << 5)

; // standard 11 bit identifier

filt.

FilterIdLow

= 0

;

filt.

FilterMaskIdHigh

= 0

;

filt.

FilterMaskIdLow

= 0

;

and I am not sure what ID's will be captured by the CAN periphery. I expect that

all CAN frames will be captured because the mask has all bits zero. Is it correct?

If it is incorrect what ID's will be captured?

Thanks.
