keil bug? warning #61-D wrong evaluation

Dear all,

My compiler throw a waring "warning: #61-D: integer operation result is out of range" but I think is a bug of the compiler because it have no sense. This is the warning line:

GPIOB->CRL &= ~(0xF << (7 * 4))

0xF << 28 times is in the range of the CRL register... can anybody tell me the reason of this?

Thanks for all

hehe... of course, is more probable that the supossed bug is a error in my code instead of bug...

Thanks
