point to main entrance.

What version of the product are you using? On what operating system?

Please provide any additional information below.
After debugging I had an instruction to reset sample_count in the set of 
instruction conditioned by if (sample_count > ALMOST_ENOUGH_SAMPLES) after 
udb_5V and udb_vcc filterings.
I do not understand why anybody seems to encounter this probably division by 
zero when sample_count reach 0xFF+1
