You are requested to implement a bit stuffer using an ARM Cortex$-$M microcontroller. A bit satffer accepts an incoming sequence of bits. If there are $3$ consecutive is in the the incoming sequence, a $0$ is inserted into the sequence. If there are $4$ consecutive Os in the incoming sequence, a $1$ is inserted into the sequence. E$.$g$.$ if the incoming sequence is $0000001101111($LSB is received first$),$ the outgoing sequence is$\_1\_000\_1\_0001101\_0\_111$ with the inserted bits in bold and separated by Each incoming bit lasts for $50$uS$.$The incoming sequence is fed to pin PB$4,$ and the outgoing sequence is to be output at pin PAG. Write a program$/$flow chart to implement the bit stuffer. Program the GPIO, and timer registers accordingly Assume that the incoming sequence that is fed to the microcontroller starts after giving enough time for the initialization part of the program
