Consider a serial port operating with a baud rate of 10,000 bits per second. Draw the waveform occurring at the PS1 output (voltage levels are +5 and 0) when the ASCII ‘A' ($61) is transmitted on SCI0. The protocol is one start, eight data, and one stop bit. SCI0 is initially idle, and the software writes the $61 to SCI0DRL at time = 0. Show the PS1 line before and after the frame, assuming the channel is idle before and after the frame.
