USART2 TC interrupt timing

I am using the TC (transmission complete) interrupt on USART2 to detect end of transmission of a packet.  I have noticed that the interrupt isn't triggered until approximately 3.5us after the last byte is transmitted.  The baud rate is set to 115200, so 3.5us is about 40% of a bit time.
Is this the expected behavior?  Can the time be adjusted?  I would like the TC interrupt to trigger as soon as the last byte is transmitted.
