Each ATmega128 USART module has two flags used to indicate its currenttransmitterstate: the Data Register Empty (UDRE) flag and TransmitComplete (TXC) flag. What is the difference between these two flags, andwhich one always gets set first as the transmitter runs? You will probablyneed to read about theData Transmissionprocess in the datasheet (includ-ing looking at any relevant USART diagrams) to answer this question

The ivanpah solar thermal power plant cost $2.2 billion to build. the gross plant electric output is 392 mw, and the net output is 377 mw. the planned capacity factor was 27.4%, but the actual capacity factor in 2016 was 20.5%. at best the plant thermal efficiency appears to be 18%. in addition, for the daily startup process, the solar plant also burned 1.3x10^12 btu of natural gas in 2016. the cost of natural gas in 2016 was about $2.5 per million btu. assuming a levelized annual fixed charge rate of 7%, determine (a) the capital cost (c/kwh) and (b) the fuel cost (e/k wh) for the electricity in 2016.
