Dear all,
I would like to know if there is a way of either:

1) Adding more mnemonics to the built-in assembler language defined in Notepad++, to tailor it to some custom microcontrollers' assembly language, or

2) Reuse the existing assembler language definition as a "template" to create a user-defined language to completely match a custom assembly language (and thus avoiding to define all the assembler features from scratch).

Thanks in advance for any help.

Regards, JL.
