Check bits in the CCR

I'm sorry if this has been answered before but i could not find a solution.

Background, using CodeWarrior 5.7, Chip is type HC12S and programming in C.

I'm performing a 16bit x 16bit multiplication and need to check if there is an overflow. I assume i should just check the relevant bits in the CCR but i'm not sure how to do this programmically.

Any help would be much appericiated.

Thank you.
