Subject: counter: Let user decide how to handle the initial dead_cycles state
X-Git-Url: https://sigrok.org/gitweb/?p=libsigrokdecode.git;a=commitdiff_plain;h=d52bd4f2ca95cf9e19e7a2a18543dacb0dd2edfe

counter: Let user decide how to handle the initial dead_cycles state

edge_off and word_off are not included in the if block because a user may
want to use edge_off to dismiss unwanted clocks instead of dead_cycles.
