The following line in USBHAL_KL25Z.cpp would generate a warning in GCC
because of a potential operator precendence issue:
return((USB0->FRMNUML | (USB0->FRMNUMH << 8) & 0x07FF));
This would have been interpreted as:
return((USB0->FRMNUML | ((USB0->FRMNUMH << 8) & 0x07FF)));
since & has higher precedence than |
I switched it to be:
return((USB0->FRMNUML | (USB0->FRMNUMH << 8)) & 0x07FF);
Since it makes more sense to & with 0x7FF after having merged the lower
and upper bytes together rather than just the upper byte. It should
have resulted in the same value either way.
