On Feb 21st 2014, the EU foreign ministers and Yanukovich signed on a deal where there would be speedy elections — that would most certainly remove Yanukovich from power, somewhere in spring.

But on Feb 22nd, the protesters refuse that deal and seize Yanukovich's palace, stripping him of power immediately. After which he flees.

It's that seizing of the palace and rejecting the EU-brokered deal is what is usually called "the coup".

The deal signed on Feb 21st 2014 says:

1. Within 48 hours after the signing of this agreement will be adopted, signed and promulgated a special law that will restore the action of the Constitution of 2004, as amended by this time. The signatories declare their intention to create a coalition and form a national unity government within 10 days thereafter.

On February 22, 2014 as allowed by Article 111 of the Ukrainian Constitution, Verkhovna Rada decided to impeach Yanukovich with 328 votes for, 0 against and 122 not present or abstaining.

According to the Constitution of Ukraine, impeachment would have involved a) formally charging the president with a crime; b) a review of the charge by the Constitutional Court of Ukraine; and c) a three-fourths majority vote – i.e. at least 338 votes in favor – by the Rada.

Of that three — that all had to happen — exactly zero happened. Instead, the Verkhovna Rada declared that Yanukovych "withdrew from his duties in an unconstitutional manner" and cited "circumstances of extreme urgency" as the reason for early elections.

This can be taken to a direction of "democratic transfer of power under extraordinary circumstances". This also can be taken to a direction of "unconstitutional coup d'etat". The direction depends on the goals one's trying to achieve.
