Flags (CEUAPRSF)

ECN bits (used when ECN employed; else 00)
	CWR	(1 = sender has cut congestion window in half)
	ECN-Echo	(1 = reciever cuts congestion window in half)
U		(1 = Urgent pointer valid)
A		(1 = Acknowledgement field value valid)
P		(1 = Push data)
R		(1 = Reset connection)
S		(1 = Synchronize sequence numbers)
F		(1 = no more data; Finish connection)

So what are the flags in our example?
Our hex characters are 10 so we break that into binary
0001 0000

C	E	U	A	P	R	S	F
0	0	0	1	0	0	0	0

The flag in our example is an A (acknowledgement)
