Many thanks for these new files.

I forgot to mention - the updated library files for the Q43 also include a fix for the EEPROM read routine, where reading eeprom did not work unless a write was done first.

Thanks very much.

There's a new version of DT_INTS-18xv that fixes a mistake with the K42/K83 INT0 definitions.
(Thanks to Henrik who found it).
