$3.(25$ points$)$ UART Serial Communication

A$.(10$ points$)$ Suppose you want to send the ascii character $$A$$ using $7$ bits and an odd parity bit. What will the value of

the parity bit be$?$ What would the value of the parity bit be if you sent $$A$$ using $8$ bits $($the last $7$ bits of the ascii value$).$

B$.(15$ points$)$ USCI$0$ is configured in the UART mode to transfer $19,200$ bits$/$second$,7-$bit characters, no parity, and two

stop bits. How many processor clock cycles $($MCLK $=2^21$ Hz$)$ expire during the time USCI needs to send one character

over the UART? Hint: Don$$t forget about the first bit that$$s transmitted in a data frame.
