X-Git-Url: https://sigrok.org/gitweb/?p=libsigrokdecode.git;a=commitdiff_plain;h=e663ab183cc55fbff23da01c0fda06d366b7130b

counter: add support for user specified initial counter values

Introduce options for the initial edge and word counter values. Default
to 0 for compatibility with the previous implementation. This fixes
