Notes
The 82C710 chip family are composed of several sub units. Future chips in the family may have some sub units which are incompatible with earlier versions, while leaving the functionality of other sub units unchanged. This call returns a feature mask, sub fields within which show the ‘compatibility level’ of each sub unit. Differing values of a sub field indicate incompatible versions of the corresponding sub unit. A sub field of zero indicates that the sub unit is not present.
