Consider the oscilloscope trace of figure Q$2,$ the yellow trace of which is the

output from a UART sending serial data, and where edges of the green$/$blue

trace delimit the software loop triggering data transmission.

i$)$ How many bits are being sent per software loop? $[2]$

ii$)$ What is the baud rate of the transmission? $[3]$

iii$)$ What ASCII character$($s$)$ are being sent? You may find the ASCII table

at the end of this paper helpful. $[4]$

iv$)$ State the purpose of the bit indicated with a red arrow, and explain how

if fulfils its purpose. $[3]$

v$)$ The receiving UART is set to $19200$ baud. What data would be received

if any?
