a$.$ In a given $8086-$based system that uses the isolated I$/$O address space, port address $0$F$220$h is used as an input port for measuring the humidity $($the port size is one byte$).$ Write Assembly language instructions to read port $0$F$220$h continuously to monitor the humidity. If the value received from the port is greater than $30$d$,$ then the continuous monitoring of the humidity should stop, and a value of $-1$ should be stored in register CL$.$
