MC9S08GB32CFU: Identify mask revision with code?

[BlkStang]

Although I'm specifically working with a GB32CFU, this question could apply to other variants of the 9S08 family:

Is it possible to read the silicon mask revision (e.g. 3L31R) my code is running on?

We have increasingly stringent configuration controls being implemented and am being asked if we can automatically detect and react to an unexpected mask revision...

System Device Identification Register (SDIDH, SDIDL) claims to have a revision number,

"The high-order 4 bits of address SDIDH are hard coded to reflect the current mask set
revision number"

But it seems on some parts the spec seems to imply they are always 0.

Looks like I can get a revision number from 0-F. This will probably work for me.

Thanks very much.
