$1.[2$ points$]$ What are the differences between the Cortex$-$M$4$ processor and the Cortex$-$M$3$ processor? Among the $3$ types of processors: Application processor, Real$-$time processor and Microcontroller processor, the STM$32$L$432$KC microcontroller belongs to which type? $2.[2$ points$]$ In cases where ASCII characters are transmitted from one device to another, a simple error detection mechanism can be implemented using a parity bit. What will be the $8-$bit code if an ASCII $"$ C $"$ is sent and the configuration is an even parity?
