I need to have an interrupt as soon as the last bit (stop bit) of the last character in TX FIFO was really transmitted (shifted out). In other words, I'd like to have an interrupt on TEMT flag in LSR register.
I need a similar interrupt to TXC (transmit complete) in AVR MCUs from Atmel.

After reading user manual, I didn't understand if this interrupt is present or not in LPC43xx USART.
